Knife Making Forge

Best Knife Making Forge Knife making is a great craft to learn. It’s always satisfying to build something with your own two hands, and you can make a great living forging knives as well. However, it’s difficult to make a knife with your bare handles. Having the proper tools is important to make sure that you can work efficiently and precisely. A good knife making forge can be the difference between a great knife and a mediocre one.

One of the quintessential tools for knife making is the forge. A reliable, well built forge is an essential tool for any knife maker. I have made a lot of knives in my time, and used a lot of forges. In this article, we’ll discuss what to look for when buying a knife making forge, then will go over a number of reviews of a variety of forges, and will provide a number of recommendations to help you find the product that is the best for you.

What to Look For in a Knife Making Forge

Knife making forges are a sizable investment. To make sure that you get a product that works for you, there are a number of things to consider. A few factors that I keep in mind are the number of burners needed, the compatibility of the forge with my parts (such as my propane tanks, if using a propane forge), and the size of the forge.

Number of Burners

Some forge burners come with multiple burners, whereas other models come with a single burner.

Single burner forges tend to be less expensive than double burner forges. In many cases, you’ll only be working with one forge burner regardless, so a single burner can be more than enough for a ton of use cases.

Double burner forges tend to be cheaper than purchasing two entirely separate single burner forges. This can save you a good amount of money if you want to have multiple burners.

In general, it is uncommon for premade knife making forges to have more than two burners, although you can also build custom knife forges for such cases, if desired.

Forge Size

Forges come in a wide variety of sizes. Some forge designs are small and basic; others are larger. If you’re working on a basic knife making product, such as a railroad spike knife, you’ll have a good time with a smaller forge. If you are working on a larger project, a larger forge may be required. Forges of all sizes can be great, just keep in mind what kind of projects you’re going to be working on.


There are a number of different types of burners that are compatible with different setups. If you’re looking for a propane burner, for example, you want to consider whether you are using a 20 pound propane tank or a 100 pound propane tank. Different burners may be designed to connect to different tank sizes. While you can make modifications to your burner, you want to be aware in advance as to whether or not you will need to make those changes.

Knife Making Forge Reviews

After testing a number of different forges for knife making, I’ve put together a number of reviews of a number of different products. These reviews go over the pros and cons of different models, and make a number of recommendations. Whether you’re looking for the very best, top-of-the-line forge, or if you’re looking for a basic, small forge, there are great knife forges out there for you.

Hell's Forge Portable Propane Double Burner

Hell's Forge Portable Propane Double Burner
688 Reviews
The Hell’s Forge Portable Propane Double Burner is a double forge burner. The forge is capable of going up to 2,300 degrees fahrenheit. This forge is large, which provides a sizable workspace. The product also comes with a container of refractory coating that you can apply as needed. The product has a one inch high density ceramic fiber blanket. There are also two full size fire bricks for the bottom of the forge.

This was the first forge that I tested for this article, and I was impressed at how easy it was to set this one up. The large size is great, it gives you a lot of space to work with the optimal places for getting the temperatures you want for different times. Based on how much propane I used when forging a test-knife, you could likely forge at least three or four knives with a single bottle of propane (of course, this depends on what size propane container you’re using).

Overall, this was the best knife making forge that I tested, and is one of the best I’ve used in my life. This is quite a high quality product, and if you want the best-of-the-best, then look no further. This is probably my favorite forge right now, and based on the quality, I expect that I’ll continue to be using this forge for years to come.

Double Burner Propane Forge

This double burner propane forge goes up to 2,600 degrees Fahrenheit. It was built with 16 gauge (1.5 millimeter) metal sheets. The gas pressure regulator connection is designed to fit for most western countries; make sure to check for compatibility.

This is a nice forge for the price that it’s listed at. I found that I needed to purchase some refractory cement to coat the insulation on the burner. But, that was fairly straightforward. The set up was easy, and after a few minutes I had it ready to go. You may also want to adjust the gas-to-air ratio when setting up your forge. After using this fairly extensively, I haven’t run into any leaks or build-quality issues, and it’s still working well.

The Hell’s Forge is higher quality than this, but this is still an excellent product. It comes at a great price for the quality, and you’ll be happy with this purchase. This is a good extra set of burners for a professional, or a good higher-end product for a hobbyist or similar.

This forge is a single burner propane forge, capable of hitting up to 2,600 degrees Fahrenheit. The forge has a one-inch thick ceramic fiber blanket. The device comes with a stand as well.

This forge is a bit small, but does the trick for plenty of simple projects. This is a solid choice for a beginner’s forge. Easy enough to set up as well. I preferred the forge in the review above this one a little more than this product, but this is a decent alternative that is comparable in terms of performance.

Hell's Forge MAX Propane Forge Double Burner Unit

The Hell’s Forge MAX is a double burner propane forge made in the United States. The burner is capable of temperatures of up to 2,300 degrees Fahrenheit. This is a large forge, and provides plenty of working space. There is a one-inch thick ceramic blanket. The product identifies its selling point as having “5x thicker steel than competitors.”

Like the Hell’s Forge burner at the top of this list of reviews (the first entry), this is a great product. Shipping was quick, and the product was easy to assemble out of the box. The forge heats up quickly and I was able to forge a railroad spike knife easily.

The only reason I would shy away from this product is because I preferred the first Hell’s Forge burner to this model, even though this one is a bit more expensive. Don’t get me wrong, there are some advantages to this model, but the first Hell’s Burner model we reviewed is perfect, at least for me.

The Simond Store portable propane forge is a single-burner forge with a temperature capacity of 2,600 degrees Fahrenheit. This was made with 16 gauge stainless steel and is lined by a one-inch thick ceramic fiber blanket. This includes one fire brick.

This forge comes at an excellent price, while still providing a good amount of value. The product works well and is holding up, even though I’ve been using it on and off while testing it over the last few months. It takes a few minutes to heat up, but that’s about par for the course. This is pretty efficient in terms of propane use, and you could use it all day and maybe go through a half a tank of propane.

The fire brick that comes with this forge is decent, and it’s a nice add-in to provide a little extra value. However, you may want to pick up a a few extra fire bricks at your discretion, depending on how much you use the forge and so on.

All-in-all, this is a pretty solid forge. Check it out if you’re looking for something decent at a reasonable price.

Our Final Thoughts

While there are a ton of good forges out there, you might want to narrow it down to a single purchase. Out of all the forges reviewed in this article, I would lean toward one of these three products.

In terms of the best product overall, the Hell’s Forge Portable Propane Double Burner is excellent. This knife gives you a huge amount of space to work with, which is excellent. This is a huge plus both in terms of making it easier to do smaller projects, but also making it possible to work with larger blades.

In terms of the best bang for your buck, the Double Burner Propane Forge is my top pick. I needed to pick up some more refractory cement to get this product running how I wanted it to, but that was pretty straightforward. I’d recommend this product as a good mid-quality pick at a solid price.

In terms of a good, reliable knife at a great price, the Vintage Style Blacksmith’s Forge Furnace is unbeatable. The bowl is fairly small, which is part of why this is a fairly inexpensive furnace. If you’re working with smaller projects, though, this is a great option. I would recommend this as the best budget furnace, for what I tested in that price range.

If you have any questions on these products, feel free to let me know! I’ll reply to your comment as soon as possible. It can be tricky to figure out what forge is right for you, and I’m always happy to help.
