If you’re looking for a detailed review of the best gas forges for knife making, you’re in luck because that’s exactly what’s covered in this section! So, keep on reading to meet each of my top eight picks with their pros, cons, and everything in between.

1. Hell’s Portable Propane Forge

Hell’s Portable Propane Forge

Key Specifications:

  • 16 Gauge stainless steel construction
  • Has a compound Bevel blade edge
  • 19” x 6.75” x 3.5” oval design 
  • 2300+ F rated
  • 1” high density coated ceramic fiber blanket

I’m kicking off this list with an excellent gas forge for knife making, which is Hell’s Portable Propane Forge. Whether you’re planning on forging hunting knives or regular kitchen knives, this forge is the perfect choice for you; here’s why.

First of all, this forge has an oval shape with dimensions of 19” x 6.75” x 3.5”, which is large enough for any knife-making task. Still, this forge is lightweight and portable enough that it won’t take much space or effort to store.

This Hell’s propane forge comes with HELLCOAT 3000 refractory coating, which I strongly recommend you apply before using the forge. Fortunately, it’s easy to apply and goes on well if you take your time with the process.

As a double burner, you can use two burners at the same time to quickly heat the forge, saving you a lot of time. On top of that, you can switch to a single burner set-up at any time if you don’t need the double burners during your knife-making. This forge is perfect for large projects, too, including sword-making if that’s something you’re interested in.

If you’re new to knife-making, there’s nothing to worry about when it comes to setting up this forge. It comes with thorough instructions that’ll make the set-up process a breeze.

It even comes with two perfect-sized fire bricks for durability and maintaining heat. However, I recommend adding extra fire bricks if you want the forge to retain heat for longer, especially around the opening.


  • Incredibly easy to use
  • Lightweight and portable
  • Beginner-friendly
  • Fuel-efficient
  • Heats up quickly
  • You can use the double burner or single burner set up


  • The propane hose is a little too short

Why settle for a single or a double burner when you can go for this Simond Store Propane Forge Triple Burner. Yes, you read that correctly, a triple burner!

Internally, the forge’s dimensions are 5.8” x 5.8” x 24,” and it has a 1” high-density ceramic fiber blanket. Construction-wise, this forge is built with 16 Gauge stainless steel grade SS-304.

While we’re on the subject of temperature, even though this Simond Store forger doesn’t have a door, it can still retain heat well, thanks to its two fire bricks that insulate the forge’s floor. Each brick is 1” x 4.5” x 9,” and combined with the ceramic fiber blanket, they insulate heat really well.

Moreover, the forge comes with a 6.5-feet hose, which is long enough for you to work comfortably. Also, it comes with a gas regulator with a manometer to maintain the forge’s pressure and Teflon tape.

Sadly, this unit isn’t the easiest to put together. I have to mention that you need to double-check that everything is in place, especially the piping for the gas, which might be challenging for a beginner.

As a double burner, this forge can get any material you’re working with to forging temperature pretty quickly. Plus, it’s efficient at maintaining that heat, thanks to the Kaowool ceramic fiber insulation. It also comes with fire bricks to help with maintaining heat.

Buying Guide: What to Look for in a Gas Forge for Knife Making

If you’re new to the world of forges and knife-making, it might be a little difficult to find a place to start. So, to make things easier for you, here’s everything you need to know before buying the first gas forge you see.

Shape and Size

Of course, the shape and size of the forge you go for can heavily affect your work. For example, if you’re planning on forging hunting knives, you need a large-sized forge that can keep up with your projects.

On the other hand, if you’ll only be working on small kitchen knives, it’s better to go for a small forge to save yourself some storage area.

Burner and Regulator

When looking for a gas forge for knife-making, you need a unit that can distribute heat evenly, heat up quickly, and maintain that heat for long periods.

Also, choosing between single, double, and triple burners depends on the kind of materials you’ll be working with. The more burners you have, the more heat your forge can withstand. If you’re unsure what to do, the safest bet is to go for a double-burner set-up that can be controlled and adjusted. That way, you can adjust the heat level to the perfect temperature for your task at hand.

Moreover, because you’re dealing with propane tanks, you need a regulator with your forge. The regulator will help you monitor the gas pressure at all times, so you’ll know immediately if something isn’t working properly.


Maintaining heat is critical when it comes to knife forging. Heat insulation can also save you money in the long run because you’ll be using less and less propane. After all, you won’t have to keep reheating the forge every few minutes.

Look for a forge with good insulation, either by having a solid door or a ceramic fiber lining. Also, fire bricks are a quick and easy solution for forges that don’t have a door.

Safety Precautions

If your forge comes with a safety precautions manual, take the time to read it and understand every point. You’ll be working with propane, fire, and extremely high temperatures, so you need to make sure all the safety precautions are taken at all times.

Cooling Methods

It’s not convenient when your forge stays hot for hours after you’ve shut it down, and it can be a safety hazard. For that, forges with built-in cooling methods are the way to go to cool down the forge when you’re not using it.

Top Gas Forge Brands for Knife Making

There’s no ultimate brand that makes the best gas forges out there, but there are a few brand names that you can trust. If you’ve noticed, some brands were mentioned more than once throughout the list simply because they manufacture high-quality units that do their job well.

Among these brands are Hell’s, Simnod Store, and USA Cast Master. I’m not saying that these are the only gas forge brands you should ever consider, but they’re a good and reliable place to start your search and see where you end up.


What Is a Gas Forge?

A gas forge is one that uses propane gas to heat up metals to forging temperature. A gas forge consists of a firebox, where all the heat is applied to the metal. Some forges have openings for airflow and to access the metal, while others have a solid door that can be closed.

How Does a Gas Forge Work?

The burner set-up uses propane and mixes it with air to cause combustion. It produces consistent heat and applies that heat to the metal to heat it up to forging temperature.

How Much Propane Does a Gas Forge Use for Knife Making?

The amount of propane your gas forge uses depends on a lot of factors, including how many burners there are, how efficient the heat insulation is, and the size of the forge. To give you a better estimation, a 100-lb propane tank should last 3-4 days of forging.

How Long Will a 20-lb Propane Tank Last in a Gas Forge?

That depends on the specifications of the forge itself and your forging skills and speed. For example, let’s say a 100-lb tank lasts 3-4 days; then, a 20-lb tank should last for a full day of work.


We hope this article helped you reach a final decision on the best gas forge for your knife-making needs. In case you need a quick memory refresh, here’s a quick recap of my top three picks.

First and foremost, Hell’s Portable Propane Forge is one you can’t go wrong with. This unit has a double burner set-up that you can control in any way you like to adjust the heat to the perfect temperature. Besides, it’s incredibly energy efficient, and it can withstand up to 2300 degrees Fahrenheit.

The second place on my list went to the Simond Store Propane Gas Triple Burner Forge. This unit’s triple burner set-up is one to die for if you’re looking for a gas forge that heats up fast. Moreover, it’s constructed with high-quality materials that ensure the high durability and longevity of this forge.

Lastly, the USA Cast Master Elite Double Burner Forge is the go-to pick if you’re on a budget. This affordable unit is made with heavy-duty steel, and it allows you to control the intensity of each burner individually.
