Buying Guide Forges for Knife Making

Best forge for knife making

It could be a little challenging to decide where to begin if you are new to the forging and knife-making industries. Here is all you need to know before purchasing the first gas forge you see, in order to make things easy for you.

Size and Shape

Of course, the size and shape of the forge you choose will have a significant impact on your job. For instance, a large-sized forge that can handle your projects is required if you intend to create hunting blades.

On the other side, using a small forge will save you storage space if you’ll just be working on tiny kitchen knives.

Regulator and Burner

You need a gas forge that can uniformly distribute heat, heat up rapidly, and sustain that heat for extended periods of time if you’re searching for one to make knives.

Additionally, your choice of single, double, or triple burners will depend on the materials you’ll be dealing with. Your forge can tolerate higher heat the more burners you have. The best option if you’re not sure what to do is to choose a controllable double-burner setup. In this manner, you may modify the heat setting to the ideal temperature for the current work.

Additionally, you need a regulator with your forge because you are working with propane tanks. The regulator will enable you to continuously check the gas pressure so that you are always aware of any problems.


When forging knives, maintaining heat is crucial. Because you’ll be consuming less and less gas over time, heat insulation can also help you save money in the long term. You won’t need to constantly warming the forge every few minutes, after all.

A forge with a solid door or a ceramic fiber liner is a sign of strong insulation. Forges without doors may also be quickly and easily fixed using fire bricks.

Safety Measures

Take the time to read and comprehend the safety precautions handbook that comes with your forge. You need to always take safety measures because you’ll be working with propane, fire, and incredibly high temperatures.

Cooling Techniques

When your forge remains hot for several hours after you’ve turned it off, it’s inconvenient and perhaps dangerous. For this, forges with built-in cooling systems are the best option for keeping the forge cold while not in use.

Best Gas Forge Brands for Making Knives

There isn’t an one company that consistently produces the greatest gas forges, but there are a handful that you can rely on. If you’ve observed, a few brands appeared on the list more than once merely because they produce reliable products of great quality.

Hell’s, Simnod Store, and USA Cast Master are a few of these brands. However, they’re a solid and trustworthy beginning to start your search and see where it leads. I’m not suggesting that these are the only gas forge brands you should ever think about.

Frequently Asked Questions & Answers

1. How Do Gas Forges Work?

A gas forge is one that heats metals to forging temperature using propane gas. The whole heat source for the metal in a gas forge is a firebox. While some forges have solid doors that may be closed, others feature apertures for airflow and access to the metal.

2. How Do Gas Forges Operate?

The burner system combines propane and air to ignite combustion. It generates steady heat and transfers it to the metal, bringing it to forging temperature.

3. How Much Propane Is Needed to Make Knives in a Gas Forge?

The number of burners, effectiveness of heat insulation, and size of the forge are just a few of the variables that affect how much propane your gas forge needs. A 100-lb propane tank should last 3–4 days of forging, to give you a better idea.

4. How Much Time Can a 20-pound Propane Tank Be Used in a Gas Forge?

That depends on the forge’s requirements, as well as your forging proficiency and speed. A 20-lb tank, for instance, should last for a complete day of labor if a 100-lb tank, as an example, lasts three to four days.
