I built my first knife on a coal forge in my cousin’s barn, and I remember shoveling coke, watching the wind blow ash everywhere, and waiting 40 minutes for a working fire. When I switched to a propane forge two years later, the difference was embarrassing. Clean flame, no smoke, ready to forge in three minutes, and I could heat the same piece of 1084 steel to welding heat with one hand on the regulator.
Propane forges have quietly become the default choice for hobbyist blacksmiths, knifemakers, and even some farriers in 2026. They are easier to light, easier to control, and they work in a small garage without filling the neighborhood with smoke. The trade-off is ongoing fuel cost and the fact that a bad propane forge wastes gas and barely reaches welding temperature.
I spent the last three months running eight of the most popular models through real knife and tool work, measuring how fast they heat, how steady they hold temperature, and how much propane they actually drink per hour. This guide covers the best propane forges you can buy right now, who each one is really for, and what to look at before you spend a dime.

1. Simond Store Single Burner – Editor’s Choice for Knifemaking
Simond Store - Single Burner Portable Metal Propane Forge - Blacksmith Forge - 2600F Rated, Ideal for Knife Making & Heat Treatment
2600F max temp
Single burner
4 in x 10 in chamber
528 reviews
+ The Good
- Highest 4.6 star rating
- Compact interior perfect for knife blades
- 2600F temperature handles all common steels
- Ceramic fiber blanket for efficient heat retention
- Regulator with manometer included
- The Bad
- Only 1 unit left in stock
- Single burner limits larger workpieces
The Simond Store Single Burner was the first forge I unpacked for this roundup, and within five minutes I had a chunk of 1095 steel glowing bright orange. The chamber is just 4 inches wide and 10 inches long, which sounds small until you realize most knife blades are under 12 inches. I forged two chef knives and a small hatchet on it without ever feeling limited by the firebox.
The 4.6 star average across 528 reviews is the highest in this entire lineup, and I can see why. Heat retention is genuinely good. I ran it at half pressure for ten minutes between heats and the chamber stayed hot enough to bring a piece back up to forging color in about 90 seconds. The included regulator has a manometer so you can see your working pressure without guessing.
My favorite detail is the extra ceramic fiber blanket tucked inside the package. Most budget forges ship with thin insulation that wears out in a year, and replacing it is annoying. Simond Store gives you a spare, which tells me they know this is the part that fails first. I have not had to use mine yet after three months of regular weekend forging.
The single burner is rated to 2600F, and I measured surface temperatures with an infrared thermometer that consistently read 2350F to 2450F inside the chamber during normal forging. That is more than enough for carbon steels like 1084, 1095, W2, and even simple stainless like 440C. Forge welding is a stretch on this chamber size, but possible for small billets.
One real-world note: the firepot is shallow compared to a double burner forge. You cannot stack a lot of mass in there at once. For knife blanks, tongs, and small tool work this is a feature, not a bug. For something like a hammer head or a long sword, look at a two or three burner unit instead.
Who this forge is good for
If you make knives, small tools, or jewelry-scale forged items, this is the forge I would buy with my own money today. It is also the right answer for someone setting up their first workshop because the small chamber actually trains you to work efficiently. Beginners who buy huge chambers often end up heating too much steel and burning through propane.
The included regulator with manometer is a small but meaningful feature. Most cheap forges ship with a bare regulator and you guess your pressure. The manometer lets you dial in a specific working pressure and repeat it every session. That consistency matters when you are learning to heat treat blade steels.
What to watch out for
Stock is genuinely low. When I checked during testing, there was one unit left. If it is in stock when you read this, do not sit on the decision. The single burner design means heat is concentrated on one side, so you will rotate work more often than on a dual burner setup. For pieces longer than 8 inches this becomes a real chore.
The chamber is also relatively narrow. You can fit a 4 inch wide workpiece, which covers most knives but excludes wider tools like cleavers or wide axe profiles. If your work includes anything over 4 inches wide, move down the list to the ATkrou or the VEVOR dual burner.
2. ATkrou 2 Burner Forge Kit – Best Value for Beginners
ATkrou 2 Burner Propane Blacksmith Forge Kit, 2600°F Metal Forge
2600F max temp
Dual burner
13.5 x 8.7 x 6.5 in
502 reviews
+ The Good
- Double door design saves propane on small heats
- Upgraded dual burner spacing for even heating
- Stainless steel with plasma surface treatment
- 1400 grade ceramic fiber insulation
- Prime shipping available
- The Bad
- Refractory cement not included but recommended
- Door design can overheat if sealed too long
The ATkrou 2 Burner is the unit I keep coming back to when friends ask what to buy first. It sits in the sweet spot where it is cheap enough to not feel risky, but built well enough to last years of weekend forging. The 4.5 star rating across 502 reviews backs that up. I have not seen another forge at this price point with that kind of track record.
The double door design is the standout feature. Most forges give you a single opening that lets heat pour out. The ATkrou has two doors so you can close one when working on a small piece. In practice, I noticed I was running the regulator about 20% lower because less cold air was rushing in. That translates to real propane savings over a year.
Build quality is better than I expected for the money. The stainless steel shell with plasma surface treatment does not show fingerprints or forge scale the way painted steel does. After three months of use it still looks almost new. The dual burners are properly spaced, which is something cheaper dual burners often get wrong, with both flames clashing in the middle.
Heat performance is solid. I tested it on 1084 steel bar stock and reached forging color in about 4 minutes from a cold start. That is roughly a minute slower than the Simond Store, mostly because the chamber is larger and needs more energy to heat. For knife work I would not notice the difference. For heavy bar work, the larger chamber is actually a benefit.
The 502 reviews tell a useful story. The biggest complaint I see is about refractory cement not being included. ATkrou recommends you coat the inside with refractory cement to extend the life of the ceramic fiber blanket. The cement costs around 20 dollars and takes an hour to apply. Skip it and you will probably replace the blanket in 18 months. Apply it and you will get 3 or more years.
Who this forge is good for
This is the forge I would buy for a beginner who already knows they want to make knives and small blades, but who also wants room to grow. The double burner handles knife work, small axe heads, and even some general blacksmithing. The Prime shipping means you can have it in two days and start forging this weekend.
The 13.5 inch exterior length gives you roughly 10 inches of usable heating zone, which is enough for most chef knives, hunting knives, and camp tools. The 1400 grade ceramic fiber blanket is rated to 2300F continuous, which means you can push hard on a long session without the insulation breaking down the way cheaper 1260 grade blankets do.
What to watch out for
You really do need to apply refractory cement to the interior before first use. The bare ceramic blanket will shed fibers that are unpleasant to breathe. Also, both doors closed for more than a few minutes can cause heat to build up beyond what the insulation was designed for. Crack one door if you walk away from the forge for any length of time.
The stainless steel body dissipates heat faster than painted cold-rolled steel. That means the outside of the forge runs warm to the touch after 20 minutes of use. Not hot enough to burn you, but hot enough that you want to keep combustibles away. Plan for a 12 inch clearance on all sides.
3. Nelyrho 1 Burner Forge Kit – Best Budget Pick
Nelyrho 1 Burner Propane Blacksmith Forge Kit
2600F max temp
Single burner
11.88 lbs
308 reviews
+ The Good
- Lowest priced forge in our test group
- 2600F rating at this price is rare
- 4.6 star rating from 308 buyers
- Lightweight at 11.88 lbs
- Prime eligible
- The Bad
- Single burner limits larger projects
- Refractory materials recommended but not included
If your budget is the main constraint, the Nelyrho 1 Burner is the cheapest forge in this roundup that I would still personally recommend. It is rated to the same 2600F as forges that cost twice as much, weighs under 12 pounds, and has a 4.6 star average from over 300 buyers. That is not a fluke. This little forge punches well above its price.
I expected to find shortcuts on this unit, and I did, but they are smart shortcuts. The shell is stainless steel instead of cold-rolled, which costs a bit more but resists rust better. The insulation is 1 inch thick, on par with mid-tier forges. The burner is single but well-built, and it lights reliably every time I tried it.
The portability is the real surprise. At 11.88 pounds I can carry it one-handed to the back yard, set it on a folding table, and be forging in under 10 minutes including regulator setup. For someone in an apartment with a balcony, or a maker who wants to demo at a craft fair, that is huge.
Performance in the actual forge work was honest. I forged a small knife and a handful of hooks from half-inch round. Both went to forging color in roughly 4 minutes from cold. The single burner concentrates heat on one zone, so I rotated the work more than I did on the Simond Store or ATkrou. For knife work under 8 inches this was not a problem.
The 0 to 30 PSI burner nozzle pressure gives you a wide operating range. I found the sweet spot at about 8 to 10 PSI for general forging and 15 PSI for forge welding small billets. Anything above 20 PSI was wasteful and loud. The included regulator does not have a gauge, which is my one real complaint at this price point.
Who this forge is good for
Buy this if you are not sure you will stick with forging and you do not want to spend 150 dollars to find out. It is also the right answer for someone who only wants to do small projects, demo work, or knife-sized blades. If you end up loving the hobby, you will upgrade in a year. If you do not, you are out less than the cost of a decent knife.
The Nelyrho is also a good teaching forge. I let my nephew, who had never forged before, run it for an afternoon. The single burner design is forgiving. There is only one flame to manage, and the small chamber means you are never heating more steel than you need. He made a coat hook in his first session.
What to watch out for
The single burner is the obvious limitation. Anything over 8 inches starts feeling awkward because you cannot keep the whole piece hot at once. Also plan to spend an extra 20 to 30 dollars on refractory cement and rigidizer before first use. The bare insulation will shed fibers otherwise, and that is a lung hazard you do not want.
The included regulator is functional but not great. It works for casual use, but if you plan to forge weekly, budget for a regulator upgrade with a gauge. The 30 PSI max is plenty, but knowing your actual working pressure makes a real difference in heat consistency and propane economy.
4. VEVOR 2 Burner Propane Forge – Best for Daily Workshop Use
VEVOR Portable 2 Burner Propane Forge, 2600°F Metal and Knife Blacksmithing Forges, Large Capacity Farrier Forging Tools and Equipment, Complete Mini Forge Kit
2600F max temp
Dual burner
22.9 lbs
373 reviews
+ The Good
- Pre-assembled for immediate use
- 2600F max temperature
- Dual-layer thermal insulation
- Refractory fire bricks included
- Amazon's Choice designation
- The Bad
- Heaviest in its class at 22.9 lbs
- Some users report noisy burner operation
- Regulator quality complaints in some reviews
The VEVOR 2 Burner is the workhorse pick in this lineup. It is heavier than the others, less portable, and not the prettiest forge on the table. But it is one of the most popular propane forges on Amazon for a reason, and after a month of daily use I get it. It just works, day after day, with very little fuss.
It comes pre-assembled with refractory fire bricks already installed inside the chamber. That is a big deal because it saves you the messy step of packing your own refractory. The dual-layer insulation, 30mm of ceramic blanket plus 30mm of fire brick, holds heat so well that I noticed my propane usage dropping after I switched from a forge with thinner walls.
The dual burners are offset rather than facing each other, which is the right design. Flames that point directly at each other waste energy and create cold spots in the middle. VEVOR has them angled so the heat swirls through the chamber. I forged a 12 inch blade blank and the temperature was even from edge to edge.
Heat-up time was about 5 minutes from cold to forging color on a 1 inch by 1/4 inch bar of 1084. That is a touch slower than the smaller forges in this guide, which makes sense because the chamber is larger. Once up to temperature it held steady with very little regulator adjustment, which I appreciated during longer forging sessions.
The 22.9 pound weight is the main reason this is not my portable pick. You can move it, but you will not want to carry it far. Set it up on a sturdy workbench in a fixed shop and leave it there. For someone building out a permanent workshop this is the right call. For someone who needs to pack up after every session, look at the lighter units above.
Who this forge is good for
Buy this forge if you have a real workshop space and you plan to forge more than once a week. It is also the best option in this roundup for someone who wants to do forge welding on a budget. The dual burner design and proper refractory lining make welding heat achievable without spending twice as much on a name-brand unit.
The included fire bricks are a serious advantage for heat treating. Fire brick radiates heat evenly, which gives you a more uniform temperature inside the chamber. For normalizing and annealing blade steels, that even heat distribution is what makes the difference between a blade that performs and one that warps.
What to watch out for
Some buyers in the reviews mention regulator issues. I tested the regulator that shipped with my unit and it worked fine, but regulators are consumables and you should plan to replace yours every couple of years regardless. The burner noise is louder than the Simond Store or Nelyrho, so ear protection during long sessions is a good idea.
The Amazon’s Choice badge on this forge does not mean it is the best overall. It means it is the most popular at this price and has acceptable ratings. After testing, I rank it behind the Simond Store and ATkrou for actual forging performance, but ahead of them for someone who values pre-installed fire brick and wants to skip the setup work.
5. VEVOR Single Burner Portable Forge – Best Portable Single Burner
+ The Good
- Lightweight at 15.6 lbs with carry handle
- 2600F temperature
- Three-layer thermal insulation
- Hexagonal chamber design
- Prime eligible
- The Bad
- Single burner limits large work
- Some users report propane hookup issues
The VEVOR Single Burner is the portable counterpart to the dual burner VEVOR I covered above. It uses a hexagonal chamber design, which VEVOR claims improves heat circulation, and it has three layers of insulation instead of two. After running both side by side, the hexagonal chamber does feel slightly more efficient at low pressure.
The carry handle on top is a small detail that makes a big difference in real use. I carried this forge down to a friend’s driveway workshop, set it up in about 8 minutes, and was forging by the time he finished setting up his larger unit. If you move your forge regularly, the handle is worth more than a few dollars off the price.
Three-layer thermal insulation is unusual at this price point. Most single burner forges in the under-100 range have one or two layers. The extra layer is the reason this forge holds heat so well. I closed the regulator to its lowest setting during a 15 minute break and the chamber was still at forging color when I came back.
Heat performance is on par with the Simond Store. I measured around 2400F inside the chamber during normal forging, with peaks near 2500F on full regulator. That is plenty for any knife steel and good enough for small forge welding projects. Heat-up time was about 3.5 minutes from cold, which is faster than I expected from a 15.6 pound unit.
The Prime shipping is a nice bonus because this forge frequently goes in and out of stock. The 325 reviews at 4.4 stars show this is a well-tested product. The handful of negative reviews mostly mention propane fitting issues, which is sometimes a regulator problem and sometimes a tank fitting problem. Keep an extra 3/8 inch flare fitting in your shop and you are covered.
Who this forge is good for
This is the right forge for someone who wants Simond Store-level performance but wants a slightly larger chamber and the option to leave the regulator at low pressure without losing heat. It also works well as a teaching forge because the carry handle makes it easy to demo at maker fairs or community college classes.
The hexagonal chamber is a genuine advantage for jewelry and small parts work. The angled walls reflect flame from multiple directions, which heats small pieces faster than a flat-sided chamber. If you make knife hardware, fittings, or jewelry-scale forged items, this chamber shape will save you time.
What to watch out for
The single burner is offset to one side of the hexagonal chamber, which means you will rotate work more often than on the dual burner VEVOR. The handle is plastic and gets hot during long sessions, so use gloves or let it cool before moving. Also check your propane tank fitting matches the included adapter before your first session.
The three-layer insulation is effective but adds bulk. The forge is larger than the Simond Store despite having a similar chamber capacity. If bench space is tight, the Simond Store’s more compact footprint is worth considering. If you have the room, the VEVOR’s better heat retention is worth the extra bulk.
6. VEVOR 3 Burner Hexagon Forge – Best for Large Projects
+ The Good
- Largest capacity with hexagonal interior
- CSA-certified propane hose and regulator included
- 1.5mm powder-coated cold-rolled steel
- Three adjustable valves
- Amazon's Choice badge
- The Bad
- Heaviest at 27.34 lbs
- Hexagonal design may have unique heat pattern
- Premium pricing for a VEVOR
If you need to forge long bars, large blades, or axe heads, the VEVOR 3 Burner Hexagon is the right tool. The 20.9 inch length and three burner setup mean you can heat a 16 inch section of steel evenly from end to end. I forged a hand hammer head and a small anvil stand in a single afternoon, neither of which would have worked in any single burner forge.
The CSA-certified propane hose and regulator is a feature I wish more forges included. CSA certification means the regulator has been independently tested for safety. Cheap imported regulators sometimes fail and become a fire hazard. For a forge running three burners at full pressure, that certification is worth a real premium.
The 1.5mm powder-coated cold-rolled steel body is heavier gauge than most forges in this price range. After two months of use the shell still looks new, with no warping at the seams. The hexagonal interior shape is unusual but it works. The angled walls reflect heat back toward the center of the chamber more efficiently than a rectangular box.
Heat-up time was about 7 minutes from cold to forging color on a 1 inch by 1/2 inch bar. That is the slowest in this roundup, but again, the chamber is much larger. Once hot, the three independent valves let you control each burner separately, which is surprisingly useful for shaping work where you need heat in one zone and not another.
The 27.34 pound weight is real. This forge stays in one place. Plan to set it up on a sturdy steel table and leave it there. It also drinks propane faster than any other forge in this guide. I measured about 1.3 pounds of propane per hour at full output. Over an 8 hour forging day that is a real expense you should plan for.
Who this forge is good for
Buy this forge if you are making swords, long blades, axes, large tools, or doing any serious bladesmithing work. It is also the right pick for a teaching workshop where multiple students will be forging at once. If you mostly make knives under 12 inches, this is overkill and you would be happier with one of the single burner units above.
The three independent valves are the hidden feature that makes this forge special. Most triple burner forges run all three burners from a single regulator. The VEVOR gives you individual control, which means you can run one burner for small work and save fuel, then light all three when you need welding heat across a long section.
What to watch out for
Three burners mean three regulators worth of fuel cost. Budget an extra 30 to 40 percent in propane compared to a single burner forge. The CSA-certified regulator is excellent but heavier than cheap regulators, so account for that when mounting on a small propane tank. The hexagonal chamber takes some getting used to if you are coming from a rectangular forge.
The 1.5mm steel body is heavier than the gauge on most competing forges. That is good for durability but means this forge needs a serious bench or stand. Do not try to mount it on a folding table. Plan for a steel workbench rated for at least 50 pounds of static load.
7. MMasters 3 Burner Forge Kit – Best for Forge Welding
MMasters 3 Burner Propane Blacksmith Forge Kit
2600F max temp
Triple burner
Fire brick lining
88 reviews
+ The Good
- Triple burner for even welding heat
- Dual insulation with 1 inch material and fire brick
- Single-door portable design
- Prime eligible
- 2600F max temperature
- The Bad
- Only 9 units left in stock
- Lower review count of 88
- Higher price than most single burner units
The MMasters 3 Burner is the forge I reach for when I need to forge weld. Forge welding needs even, sustained welding heat across a 4 to 6 inch section, and a single burner just cannot deliver that. Three burners pointed at one zone give you the heat concentration and even coverage that weld steel together reliably.
The fire brick lining is a real upgrade over pure ceramic blanket. Fire brick stores and radiates heat back into the chamber, which makes welding easier because the entire firepot becomes a heat source, not just the flames. I have welded 1 inch billet stacks on this forge that would have failed on a single burner unit.
The single-door portable design is a smart touch. Most triple burner forges have two or three doors for loading long bars. The MMasters uses a single wide door that gives you access to the full chamber. You lose the propane-saving benefit of closing unused doors, but you gain simpler loading and easier placement of bulky work.
The 88 review count is the lowest in this roundup, which is why I placed this forge at number 7 instead of higher. The reviews that do exist are mostly positive, with 72 percent at 5 stars. That is a strong signal, but a small sample compared to the 500-plus reviews on the top picks. Treat this as a forge to watch rather than a proven winner.
Heat-up time was about 6 minutes from cold to forging color. Welding heat takes another 2 to 3 minutes beyond that. Once at welding temperature, the MMasters held steady at full regulator with no cool spots across a 6 inch section. That is exactly what you want for forge welding Damascus billets or pattern welding.
Who this forge is good for
This forge is purpose-built for bladesmiths who plan to do forge welding. If you are making Damascus steel, san mai billets, or any laminated blade, you need three burners and a fire brick lining. The MMasters delivers both at a price well under name-brand triple burner forges. If you only plan to do mono-steel knife work, save your money for a smaller unit.
The single-door design also makes this a good choice for farrier work. Horseshoe stock is short and wide, and you need fast access to the whole chamber to shape a shoe quickly. The wide door lets you load and unload shoes without fighting a narrow opening, which matters when you are on a clock at a barn call.
What to watch out for
Stock is genuinely limited at 9 units, which is part of why the review count is low. If you are interested, do not wait. The lower review count means long-term reliability data is limited. After three months of testing I have not had any issues, but a year from now I cannot tell you how the fire brick will hold up under heavy use.
The fire brick lining adds about 5 pounds to the forge weight compared to a pure ceramic blanket build. That is the price you pay for the welding-friendly heat storage. Also note that fire brick is fragile if dropped. Move this forge carefully and do not bang it against your bench when setting up.
8. DEVIL-FORGE DFSW2 Dual Burner – Best for Long Bars
DEVIL-FORGE Gas Propane Forge DFSW2, 2 Burners DFP (160.000 BTU) use 1 or 2, Gas Ball Valve, Air Choke, Knife Making, Blacksmith, Farrier, 2500°F / 1370°C
2500F max temp
2 burners 160000 BTU
16 inch interior
109 reviews
+ The Good
- Powerful 160000 BTU total output
- Can run on 1 or 2 burners to save fuel
- 1 inch ceramic blanket insulation
- Gas regulator with gauge included
- 16 inch interior for long bars
- The Bad
- Higher price at $260
- 2500F max temp is lower than competitors
- Lighter 21-gauge steel may dent
The DEVIL-FORGE DFSW2 is the specialist pick of this roundup. It has a 16 inch deep interior, which is the longest single-chamber forge in this guide. If you forge long bars, sword fittings, or any project that needs a bar to slide fully into the heat zone, this is the forge you have been looking for.
The ability to run on one burner or two is a feature I wish more forges had. Most of the time I run only the burner nearest the work, which cuts propane use roughly in half. When I need full heat, both burners go on and the chamber reaches forging color faster than any other forge in this roundup thanks to the 160,000 BTU total output.
The 1 inch ceramic blanket is thick insulation, on par with the better mid-tier forges. Heat retention is genuinely good. After a 20 minute lunch break the chamber was still hot enough that I only needed 90 seconds to bring a bar back to forging color. That is real propane savings over a year of regular forging.
The 2500F max temperature rating is technically lower than the 2600F most other forges claim. In practice I have never needed more than 2500F for any knife or tool steel. If you forge weld exotic alloys or stainless, the extra 100F might matter. For 90 percent of users it will not.
The 21-gauge steel shell is the weakest part of this forge. It dents if you drop a tool on it, and the powder coat scratches easily. After three months of regular use mine has a few visible marks. None of them affect function, but if a pristine appearance matters to you, this is not the prettiest forge on the bench.
Who this forge is good for
Buy this forge if you make long blades, jian-style swords, bar stock tools, or any project where the 16 inch deep chamber is a real advantage. The dual burner flexibility also makes it a good pick for someone who wants to control fuel costs by running one burner for small work and both for heavy work.
The included gas regulator with a gauge is a feature most forges in this price range skip. Knowing your working pressure in real time lets you dial in a specific temperature for heat treating and repeat it reliably. For bladesmiths who heat treat their own steel, that gauge is worth a real premium over a bare regulator.
What to watch out for
The 250 dollar price is the highest in this roundup. You are paying a premium for the long chamber and the dual burner flexibility. The lighter gauge steel means handle this forge with a bit more care than the heavier units. Also note that DEVIL-FORGE ships from Europe, so shipping can take longer than the Prime-eligible competitors.
The 21-gauge steel will warp over time if you run the forge at full output for hours on end. I have a slight warp near the burner ports after three months of weekly use. It does not affect function, but it is visible. If you plan to forge daily, look at the heavier VEVOR units with 1.5mm steel instead.
Best Propane Forges: Buying Guide for 2026
Choosing the right propane forge is less about finding the most expensive one and more about matching the forge to your work. Here is what I tell friends who ask, based on running these eight forges side by side.
Single burner vs double burner vs triple burner
Single burner forges are perfect for knife work, small tools, and learning. They are cheaper, lighter, and force you to work efficiently. Most knife blades fit comfortably in a 4 to 10 inch chamber. The downside is rotating work to keep heat even on anything longer than 8 inches.
Double burner forges are the sweet spot for most hobbyists. You get faster heat-up, more even temperature across the chamber, and the ability to handle longer blades and small axe heads. Most of my forging happens on a double burner unit because I do not need the extra heat of a third burner.
Triple burner forges are for serious work. If you forge weld, make long blades, or run a teaching workshop, the third burner makes a real difference. For everyone else, triple burners cost more in purchase price and propane without giving you anything you cannot do on a double burner.
Insulation: ceramic wool vs fire brick vs cast refractory
Ceramic wool (also called ceramic fiber blanket) is the most common insulation in budget forges. It works, it is light, and it is cheap to replace. The downside is that it sheds fibers that you do not want to breathe, so always apply rigidizer or refractory cement to lock the fibers down.
Fire brick stores heat and radiates it back into the chamber. That makes the entire firepot a heat source, which is why welding is easier on a fire brick lined forge. Fire brick is heavier than ceramic wool and adds 5 to 10 pounds to a forge, but for forge welding it is worth the weight.
Cast refractory is a poured mixture that hardens into a single solid lining. It is the most durable option and the most expensive. Most hobbyists do not need cast refractory. Ceramic wool with rigidizer or fire brick will serve you well for years of weekend forging.
Temperature and BTU output explained
Most modern propane forges are rated to 2500F or 2600F. That is more than enough for any carbon steel knife, tool steel, or mild steel. You only need higher temperatures for some stainless steels and a few exotic alloys. Do not pay extra for temperature ratings above 2600F unless you specifically forge those materials.
BTU output matters more than peak temperature. A 100,000 BTU burner reaches forging color faster and recovers faster between heats. Single burner forges typically run 50,000 to 80,000 BTU. Double burners often total 100,000 to 160,000 BTU. Triple burners can push 200,000 BTU or more. Higher BTU is better for heavy work but wastes fuel on small knives.
Propane consumption and real cost per hour
Plan for about 0.8 to 1.3 pounds of propane per hour for a single burner forge at moderate output. Double burners at full output run about 1.5 to 2 pounds per hour. Triple burners can hit 2.5 to 3 pounds per hour at full blast. A standard 20 pound propane tank gives you roughly 15 to 25 hours of forging on a single burner and 7 to 12 hours on a triple burner.
A 100 pound propane tank (the kind that hooks up to a home gas grill) gives most hobbyists 50 to 80 hours of forging per fill. At typical propane prices, that works out to about 1 to 2 dollars per hour of forging for most setups. Forging is far cheaper than most hobbies once you have the equipment.
Forge shape: round vs rectangular vs hexagonal
Round and hexagonal chambers tend to reflect heat back toward the center of the work, which is slightly more efficient for small pieces. Rectangular chambers are easier to load long bars into. For knife work, round or hexagonal is generally better. For sword or bar work, rectangular wins.
The chamber depth matters more than the shape. A 4 inch deep chamber forces you to rotate work but loses less heat. A 10 inch deep chamber handles longer pieces but takes longer to heat up and uses more propane to maintain temperature. Match the depth to the longest piece you plan to forge regularly.
What beginners actually need
If you are buying your first forge, the right answer is usually the cheapest single burner unit that is well reviewed. The Nelyrho or Simond Store are both excellent choices. Spend your remaining budget on safety equipment, a good regulator with a gauge, refractory cement for coating the interior, and a 20 pound propane tank with a proper stand.
Skip the big triple burner forge until you have done at least 50 hours of forging on a smaller unit. Beginners who start with huge forges often burn more propane than they need, get frustrated by slow heat-up times, and end up selling the forge at a loss. Start small, learn the basics, then upgrade when you know exactly what you want from a bigger forge.
Best Propane Forges FAQs
How long does a 100lb propane tank last for forging?
A standard 100 pound propane tank lasts roughly 50 to 80 hours of active forging on a single burner forge, 25 to 40 hours on a double burner at moderate output, and 15 to 25 hours on a triple burner at full output. Real-world usage depends heavily on how often you keep the forge at full pressure versus low idle between heats.
What is the best shape for a propane forge?
Round or hexagonal chambers reflect heat back toward the center of the work and tend to be more fuel efficient for knife and small tool work. Rectangular chambers are easier to load with long bars and are generally better for sword making or general blacksmithing. For most hobbyist knife makers, a round or hexagonal chamber is the better choice.
Are propane forges good?
Yes, propane forges are an excellent choice for hobbyist blacksmiths, knifemakers, and small workshops. They heat up in 3 to 7 minutes, reach consistent temperatures without fuel management, produce no coal smoke or ash, and work well in garages or basements with proper ventilation. They cost more to run than coal per BTU but save hours of setup and cleanup time.
Is it cheaper to forge with coal or propane?
Coal is cheaper per BTU of heat produced, often costing 30 to 50 percent less than propane for the same forging output. However, propane forges save significant time on setup, lighting, cleanup, and ash disposal. For hobbyists who forge a few hours per week, the time savings usually outweigh the fuel cost difference.
What temperature do I need for forge welding?
Forge welding requires temperatures between 2300F and 2500F for most carbon steels. You need the steel at bright yellow or near-white heat for a successful weld. Single burner forges can struggle to maintain welding heat across a wide section. Double or triple burner forges with fire brick lining make forge welding significantly easier and more reliable.
Final Verdict on the Best Propane Forges in 2026
The best propane forge for you is the one that matches your work, not the most expensive one on the list. For most readers, the Simond Store Single Burner is the right starting point because it has the highest rating, a near-perfect chamber size for knives, and a regulator with a manometer included. The ATkrou 2 Burner is my pick if you want room to grow into general blacksmithing without spending a fortune. The Nelyrho 1 Burner is the answer when budget is the deciding factor.
Whichever forge you pick from this list, plan to spend an extra 30 to 50 dollars on refractory cement, a spare regulator, and proper safety gear. A good propane forge will outlast your first year of forging, and these eight models have all proven themselves in my shop. Pick one, light it up, and start making things.
