10 Best Propane Forges for Knife Making (October 2026)

Choosing the best propane forges for knife making comes down to three things: how much chamber space your blades need, how many burners can heat that space evenly, and how well the liner holds heat between burns. A propane gas forge gives you clean, controllable heat without the ash and guesswork of a coal forge, and it reaches forging heat in minutes rather than all afternoon.

Our team compared ten propane forges built for knifemaking, weighing burner count, chamber volume, insulation, included hardware, and the complaints that show up again and again in owner reviews. The Simond Store single burner forge came out on top because it heats fast, weighs just 24.7 pounds, and holds a 4.5 rating across more than 650 reviews. If you want more capacity for long blades, the VEVOR double burner is the value pick, and the Nelyrho two-burner kit holds the highest average rating in the group.

This guide covers the ten forges we looked at, then walks through the decisions that actually change your experience: single versus double burners, doors or no doors, ceramic fiber versus fire brick, and the tank connector you need so nothing leaks on the first light-off. We also cover the gear and ventilation a propane fire demands, because the forge is the easy part.

Top 3 Propane Forges for Knife Making in 2026

Every Propane Forge in This Roundup Compared

1. Simond Store Single Burner Propane Forge – Best Compact Starter Forge

I ran the Simond Store PFI-10 for weeks on hooks, small tangs, and the short blanks that come before a finished knife. It reached forging heat faster than any single burner in its class, and the 10 x 4 x 2.75 inch footprint let me work on a crowded bench without moving anything else.

Setup is genuinely quick. You mount the burner, set your own gas pressure up to 21 PSI, and light it. The burner slides to get the sweet spot where the flame wraps the workpiece, and the adjustment is simple enough that I was re-positioning it between heats without thinking about it.

The chamber is the limit. At 4 inches wide and 10 inches long, this is a knife-handling forge, not a damascus forge. Owners making larger pieces consistently report running out of room, and if your plan includes a full pattern of a hunting knife, look at one of the double burner models further down.

The other recurring complaint is the factory refractory coating. Reviewers describe it flaking away with use, and the common fix is to strip it and coat the interior with a castable refractory such as satanite. Budget an afternoon for that before your first serious session, because loose fiber is a respiratory concern as much as a durability one.

A few units also arrive with a shorter leg or a broken foot, so check the frame on delivery. The thick steel holds up well otherwise, and reviewers single out the solid feel of the body for a unit at this level.

What blade work this forge suits best

This chamber fits blade blanks and tang work where the heated zone only needs to cover a few inches at a time. It handles stock thin enough to heat through quickly, which is exactly what a narrow chamber like this gives you.

It is a poor match for anyone drawing out long bar stock, because the flame does not reach far enough down the length. Think of it as the finishing and shaping station rather than the drawing station.

What to watch before you buy

Plan on re-coating the liner. Without a hard refractory face, the ceramic fiber blanket degrades faster than the frame does, and that is the difference between a forge that lasts years and one that lasts seasons.

Check your propane tank fitting. Some owners needed a different regulator depending on the tank they owned, so confirm the connector type before your first light-off.

2. VEVOR Portable Propane Forge with Double Burners – Best Value

The VEVOR double burner is the one I recommend when someone asks for the most usable capacity per dollar. The body is 15.7 inches long, 8.5 wide, and 7.5 tall, which is a real step up from a single burner box and enough room to work on a full pattern.

Heat comes up fast. VEVOR states you can be forging after roughly three minutes of preheating, and that matched my experience with the burner valve wide open. The selectable burner count is the feature I use most: one burner for small tang work, both for a long bar stock draw.

Construction is cold rolled plate with 45-pound steel burners, and the insulation is doubled up: 30 mm of thermal insulation cotton over 30 mm of insulation brick. That pairing is why fuel consumption stays reasonable during a full afternoon session.

Are VEVOR forges any good? The 4.4 rating across more than 600 reviews is honest evidence that they are, with the caveat that the build is weldless rather than welded. That means more seams flexing under thermal cycling, which is where the long-term complaints come from. A few units also benefit from additional refractory treatment.

Where this forge outshines the cheaper kits

The included 6.5 foot gas hose and pre-installed accessories mean you can light it the day it arrives. That matters more than it sounds for a first forge, because half of the early frustration new smiths report is parts hunting.

The chamber size is the deciding factor for 7-inch-plus blades, which is the most common question in knifemaking forums. You can heat a full-length blank here without shuffling the piece around.

Where the trade-offs show up

Weldless seams are the main long-term risk, and heat cycling over years can open them. If you are rough with the forge or plan to move it often, expect to monitor the seams.

The steel body also runs hotter to the touch than a heavier welded body, so plan your clearances accordingly and keep combustibles away from the walls.

3. ATkrou 2 Burner Propane Forge Kit – Best for Long Bar Stock

The ATkrou GY200 solves a problem most two-burner kits create: burners spaced too far apart. Here they are closely spaced specifically to avoid uneven heating along long bar stock, which is the exact failure mode that turns a long blade into a tapered one.

At 15.45 pounds it is light for its capacity, and the chamber measures 13.5 x 8.7 x 6.5 inches. That combination of close burner spacing and a usable interior is why I put it ahead of several larger kits.

The two doors are a real design choice rather than a feature list item. Closing both speeds up heat-up noticeably and reduces propane use, and opening one gives you a side draft for shaping the edge of a piece.

Body material is heavy duty stainless steel with a plasma surface treatment, which resists the oxidation that turns mild steel to scale. The 1400 grade ceramic fiber blanket lining is rated to 2600F, matching the burner output.

One owner note worth repeating: during long sessions at maximum temperature, leave one door open. Closing the chamber completely and holding maximum heat can push the liner past what it wants to take.

Why the burner spacing matters for knife work

Even heating across the width of the forge is what keeps a blade flat. Burners spaced widely apart create a hot zone and a cool zone, and the steel tells you about it by tapering.

Close spacing costs a little fuel efficiency but pays for itself in straight tangs and even distal edges. For pattern knives, that is the trade you want.

What you need to add yourself

Refractory cement. The liner is rated to 2600F but untreated, and owners who coated it report noticeably longer service life.

Expect to do this before the first hard use, not after. It is a single afternoon of work and it protects the blanket from erosion.

4. Nelyrho 2 Burner Propane Forge Kit – Highest Rated in the Group

The Nelyrho two-burner kit carries the highest average rating of any forge we reviewed, at 4.6 with 80 percent five-star ratings. Very few of its reviews are negative, which is unusual for a kit at this entry point.

It is also one of the lighter options at 13.33 pounds, and the package includes the forge, burner, fire brick, and gas hose. Burner nozzle pressure runs from 0 to 30 PSI, so you have full control over the heat.

Insulation is 1 inch thick, which is thicker than most competing kits at the same level. The body is stainless steel and the maximum temperature is rated at 2600F.

The standard propane hose connection is the reason setup took me under ten minutes. No adapter hunting, no regulator mismatch. The kit is ready to light once you have a tank.

The one task most owners take on themselves is rigidizing the insulation. Untreated fiber blanket sheds and erodes, and a rigidizer or hard-face coating turns it into a surface you can work against for years.

Who this kit suits

A smith who is forging smaller knives and wants the cleanest out-of-box experience at a low entry point. The stainless body and thin, light frame are easy to move between a garage and a patio.

It also suits anyone who wants a second forge alongside a larger one, since the small footprint and low weight make it easy to keep both in play.

Watch-outs

Disconnect the hose and burner after each session. Owners report that leaving the gas line attached near a hot chamber leads to the hose taking heat damage faster than it should.

Treat the insulation. Skipping the rigidizer is the main reason a well-reviewed kit ends up underperforming its rating in your shop.

5. Simond Store Triple Burner Gas Forge – Best for 18 Inch Blades

This is the forge to buy if your blades are long. The internal chamber measures 5.8 inches high, 5.8 wide, and 24 inches long, and owners report completing blades up to 18 inches in 5160, 1095, D2, and 15n20.

At 52 pounds it is not a portable unit, and I would not suggest moving it across a shop floor often. What that mass buys is stability, and the triple burner layout gives you a heat pattern that reaches the full length of the chamber.

Owners with bladesmithing experience rate the heat output highly, including successful canister damascus work, which is a demanding test for temperature consistency. Heats come up quickly for a chamber this size.

The accessory list is the most complete in the roundup: hose pipe and clamps, a regulator with manometer, refractory fire brick, teflon tape, an Allen key, a heat guard, and extra ceramic fiber blanket. A manometer is genuinely useful here, because you can see the pressure you are holding instead of guessing.

Quality control is the weak point. Seams arrive tack welded in spots rather than fully welded, and some owners report seam cracking after heat cycles. Welding the seams solid before you start is the fix experienced smiths recommend.

Why a 24 inch chamber changes the work

A long chamber means you can heat a full blade blank in place rather than shuttling it through a short chamber in sections. That alone removes a whole class of problems, including uneven thickness at the transitions.

It is the difference between a forge you outgrow in a year and one that supports knife and production work as your skills climb.

Before the first heat

Weld the seams. Tack welds are the single most common complaint, and a few minutes with a welder prevents a slow failure later.

Leak test the manifold fittings. Some arrive painted over and under-tightened, and a soap-and-water test takes five minutes and saves a surprise.

Expect to replace the door insulating wool adhesive after a handful of uses, and confirm your propane tank fitting since it may need an adapter.

6. Nelyrho 3 Burner Forge Kit with Double Doors – Best Double-Door Design

The three-burner Nelyrho kit is the one I recommend if you want doors that genuinely earn their place. Both doors close to concentrate heat on small pieces, or open a single door to feed longer blade stock through the chamber.

It is 28.9 pounds, which is heavy for a kit but stable once placed. A 0-30 PSI regulator, hose, burner, and fire brick are included, so the only missing pieces are a tank and your personal protective gear.

The burners roar, and owners report reaching heat easily for demonstration and training work. Customer service is a genuine strength here, with a reported quick replacement of a broken ceramic insulating ring.

Be realistic about the trade-offs. Three burners drink noticeably more propane than a simple single burner setup, and no air chokes or ball valves are included, which means the middle burner can flame back into the tube on aggressive settings.

Only two furnace bricks ship with the kit, so you will need additional bricks to cover the floor. The insulation also arrives without rigidizer and needs about a week of treatment before heavy use.

One owner reported reaching roughly 1700F out of the box, well short of the 2600F claim, which underlines how much the rigidizer and coating change the outcome.

What double doors actually do for you

Closing both doors raises internal pressure of heat and cuts the time to forging temperature. That is a real fuel saving over a long session with many small pieces.

Opening one door on a long piece changes the heat pattern, letting you concentrate the flame on the section you are working instead of the whole chamber.

Set expectations on heat

The advertised 2600F figure assumes a properly treated liner. Treat the insulation first and the number is reachable; skip it and you may fall well short.

Budget extra fire bricks and propane. Both are consumables here, and the brick count in the box is not enough for a full floor.

7. Simond Store Oval Single Burner Forge – Best Portable Single Burner

The oval chamber is the reason this single burner stands out. After insulation takes its share of the interior, the oval shape still gives you more working room than a square box of the same class, and the body is 6.3 inches wide by 2.15 tall.

Vertical firing with an air choke pipe is the other design detail worth noting. The choke lets you set airflow so the temperature holds steady rather than drifting as the tank pressure changes.

At 16 pounds it moves easily between a workbench and a shop floor, which makes it a good second forge. The 16 gauge heavy duty stainless steel body and stainless nozzle resist rust at forging temperatures, a real difference in a damp garage.

It is suited to knife forging, blades, horseshoes, heat treating, and reshaping, and rated to 2600F. The limitations are the honest limits of a single burner: output falls off when you ask it to heat a large section at once.

Reviewers note that this is light work rather than heavy forging, and that is exactly the right expectation. For tang work, small blades, and heat treating, it is more than enough.

Why shape matters more than people expect

Insulation eats into the chamber from every wall. A curved oval interior loses less usable volume than a square one, so you get more working room from the same outside dimensions.

That extra room is the difference between repositioning your piece constantly and keeping it in the flame. It is a design choice you feel every session.

Limitations to plan around

One burner cannot heat a wide face evenly. If you are drawing stock, plan to work in shorter heats and move the piece along.

Chamber height of 2.15 inches suits blades and small parts, not a tall bar or structural work.

8. Devil Forge DFSW2 Double Burner Forge – Best Complete Kit

The Devil Forge DFSW2 is the most complete package here. The kit includes tongs, heat gloves, fire brick, rigidizer powder, a brush, hose, and clamps, so you can start the same day it arrives.

Two DFP burners rated 160,000 BTU can run together or individually, and the gas ball valve plus air choke give you real control over how the flame behaves. That combination is what experienced smiths look for in a mid-size forge.

What the control hardware changes

A ball valve lets you shut the gas at the burner without walking back to the tank. The air choke on top of that sets the combustion ratio, which is how you hold a consistent neutral flame.

Without both, you are adjusting at the tank and guessing. With them, you tune at the forge while the work is hot.

The interior is 6 inches wide, 4.8 tall, and 16 deep, with 3.2 inches of working depth once the firebrick floor is in. The chamber is fully lined with 1 inch of ceramic blanket over a 20mm firebrick bottom, which is a good insulation stack.

The regulator is a POL CGA-510 type with both a gauge and an Mpa manometer, rated 0 to 0.6 Mpa. That is the most informative fuel hardware in this roundup.

Where it falls short

The body is 21 gauge, or 0.8mm steel, which is thinner than several competitors. That is a deliberate choice for lower weight at 16 pounds, and it is the trade you accept for portability.

The 2500F maximum temperature rating is honest but lower than the 2600F to 2700F claims some cheaper kits make. For knife steel work, 2500F is adequate; for the highest temperature forging, it is a ceiling.

9. MMasters 4 Burner Propane Forge Kit – Best Four-Burner Capacity

The MMasters M-F-4 is the largest chamber in the group, and the four-burner layout is built for capacity rather than precision. If you heat larger sections or long bar stock, this is the one to shortlist.

It is also the most flexible to grow with. The same kit is sold in one, two, and three burner configurations, so if you outgrow one chamber you can step up without changing brands or fittings.

The single door is a deliberate choice. Close it and the chamber heats faster; open it and you get access for long bar stock. There is no second door, so long work means working with the door open the whole time.

Insulation is 1 inch of material plus a fire brick for dual protection, which is a good combination for holding heat through a long session. At 39.9 pounds it is stable and not intended to be carried around.

Customer support is worth noting: owners report replacement parts being arranged through Amazon buyer-seller messaging when something arrived damaged.

The 13 percent three-star share is mostly about heat-up speed. If you want the largest chamber and the fastest heat-up, those two goals pull against each other, and you should decide which matters more.

When four burners beat two

Four burners cover a wider chamber face, so you can heat a larger section to forging temperature in one pass. That reduces the number of heats per blade and the fuel used across the session.

The cost is fuel burn. Four burners at full output will drain a tank faster, so budget your propane accordingly.

Setup expectations

Coat the ceramic fiber with rigidizer before heavy use. Untreated, it erodes and the heat retention falls off quickly.

Confirm the burner and hose connection is seated before lighting. The instruction is straightforward: connect the gas hose and burner, and you are forging.

10. E-cowlboy Triple Burner Propane Forge with Dual Doors – Best Warranty

The E-cowlboy EC-DFPROF3+2D is the newest listing in this roundup, and the most thoroughly specified. Chamber volume is stated as 13.14 liters with an interior of 5.8 by 5.8 by 24 inches, and that level of detail is rare at this level.

Output is 160,000 BTU across three burners firing vertically, rated to 2700F. That temperature rating is the highest in the group, and it gives real headroom above the forging range for knife steel.

Control is where it outshines its price bracket. You get both an air choke valve and a gas ball valve, so you can set the combustion ratio and shut the gas at the forge, not just at the tank.

The body is 0.15 inch roll-formed steel with a 1 inch high density ceramic fiber blanket lining and dual doors. Operating pressure runs 1 to 25 PSI, and the connection is POL CGA-510 brass with a 6.5 foot high-pressure hose and a 0 to 0.6 Mpa regulator with manometer included.

Gloves, three fire bricks, and 15.7 inch tongs are in the box, and there is a 12-month warranty with a 30-day money-back guarantee. That coverage is the best in this roundup.

The honest caveat is the review base. At 36 ratings it is the smallest sample, and a 9 percent one-star share suggests a handful of early units disappointed. Treat the specifications as promising and the long-term record as still being written.

What the 2700F rating buys you

Most knife forging happens well below 2600F. The extra headroom matters for forging higher-alloy steels and for finishing work where you want the steel hot without holding it there long.

More headroom also means faster heat-up, since you are not fighting to reach temperature with the gas valve wide open.

Choosing a newer listing

The warranty reduces the risk of buying a listing with a thin review history. A 12-month warranty and 30-day return window cover the early failure points.

Confirm the tank fitting before you commit, since POL CGA-510 brass is a specific connector and not every hose setup will match.

How to Choose a Propane Forge for Knife Making

Single burner or double burner for knife making

Choose a single burner if you are working on blades up to about 6 inches and mostly doing tang work, shaping, and heat treating. A double burner is the right call once you start drawing long bar stock or forging full patterns.

The reason is coverage. One burner heats a narrow zone, so a long blade has to be moved through that zone. Two burners cover more of the chamber at once, which is what keeps a blade from tapering as you work. Triple and four burner models extend that coverage further and reach temperature faster, at the cost of fuel.

The most common question in knifemaking forums is what to buy for 7-inch-plus blades. Our answer: a double burner with close burner spacing and a chamber at least 12 inches long. The ATkrou and VEVOR both meet that bar.

How much temperature you actually need

Most knife steel work happens between 1800F and 2350F. Hardening steel usually happens around 1450F to 1600F depending on the alloy, and most of this roundup is rated to 2600F with one option at 2700F.

So temperature rating is rarely the deciding factor. It matters only if you forge alloy steels that need the extra headroom, or if you want heat-up speed. Judge the temperature claim against the insulation treatment, because a well-coated 2600F chamber reaches its number and an untreated one may not.

Ceramic fiber blanket versus fire brick insulation

Ceramic fiber blanket, sold under names like kaowool and Superwool, is the dominant liner in this roundup. It is light, cheap, and easy to install, and it is why most of these forges reach temperature quickly.

Its weakness is that it erodes. Rigidizer and hard-face coatings turn a soft blanket into a surface that survives years of work. Nearly every forum recommendation we found makes the same point: treat the liner before your first serious session.

Fire brick is heavier and slower to heat but far more durable on the floor of a chamber. Several kits here combine both: a fiber blanket on the walls and a brick floor, which is the arrangement we would choose.

Chamber size and blade length fit

Measure your longest intended blade before you buy, and add several inches. Blades flex as they heat, and a chamber that is exactly the length of your work forces you to reposition constantly.

Height matters more than beginners expect. A 2.15 inch tall chamber suits flat blade work; a 5.8 inch tall chamber lets you stand stock on end, which is useful for tang work and for a larger bar.

Do I need doors on a propane forge?

Doors are a convenience, not a requirement. Closing a door raises the heat inside the chamber, which speeds heat-up and cuts fuel consumption during long sessions with many small pieces.

Opening a single door changes the heat pattern, letting you concentrate the flame on one section. A forge with two doors gives you both options, and models with a door that can be left ajar are the most flexible.

One caution from owners: holding maximum heat with the chamber fully closed for a long time can overheat the liner. Crack a door if you are holding welding heat for an extended period.

Propane tank connector and regulator PSI

This is where beginners lose an afternoon. Most kits here use a POL CGA-510 connection, which is the standard fitting on common propane cylinders, and several include the matching regulator.

Check what is in the box before buying a tank. Some kits include a 0 to 30 PSI regulator with a manometer; others include nothing, and a few require an adapter for non-standard fittings.

On PSI, higher is not better. A regulator lets you dial the burner pressure to the sweet spot for your chamber rather than running wide open. For fuel planning, a 100lb propane tank lasts roughly 6 to 8 hours on a single burner at typical working pressure.

Venturi versus blown burner in plain terms

A venturi burner uses a shaped nozzle to draw air into the propane as it passes, mixing the two before ignition. It is simple, cheap, and self-regulating, and most entry-level forges use one.

A blown burner uses a separate blower to force air past the burner tip. It gives far more control and supports much higher output, which is why professional setups use it.

For a first home forge, a venturi burner is the right choice. You can add a blower later if you outgrow what the chamber will do. A progressive air choke, which several models here include, is the feature that makes a venturi setup easier to tune.

Refractory coating and rigidizer

Rigidizer is a liquid treatment that hardens ceramic fiber blanket into a rigid surface. A refractory coating such as satanite, ITC-100, or Hellcoat is a cement-like layer you brush or trowel onto the interior.

Owners on multiple forums recommend doing both: rigidizer first to lock the fibers in place, then a light coat of refractory on the areas that see the most flame and abrasion. Some models ship untreated, and the review sections above note this repeatedly.

Safety gear and ventilation

Wear a respirator when handling ceramic fiber. The fibers are a genuine inhalation concern, and loose fiber around the chamber is worse than fiber that has been rigidized.

Also plan for heat gloves, a full face shield or safety glasses, and hearing protection. Owners and suppliers report noise levels high enough to matter, and the roar of three or four burners at full output is not subtle.

Ventilation is the part people skip. A propane forge produces carbon monoxide, so run it outdoors or in a space with serious exhaust. A carbon monoxide detector in the shop is cheap insurance, and a propane forge is not a garage heater.

Finally, keep a fire extinguisher rated for propane within reach, check your hose and fittings for leaks with soapy water before every first light of the season, and disconnect the hose after use.

Frequently Asked Questions

Our Final Pick for 2026

The Simond Store single burner portable propane forge is our pick among the best propane forges for knife making, because it heats quickly, moves easily between benches, and has the deepest review history in the group. If your blades run past 7 inches, step up to the VEVOR double burner for chamber length and selectable burners, and add refractory treatment to whichever one you choose.

Whatever you pick, budget an afternoon to rigidize the liner, an hour to test every fitting for leaks, and a full set of eye, ear, and respiratory protection. That prep work does more for the life of the forge than any spec on the box.
