HotShot HS-24K Knife Heat Treat Oven
The HotShot HS-24K is a professional-grade knife oven designed specifically for knife makers, bladesmiths, and blacksmiths who demand consistent, high-performance results in their own shops. With a spacious 24" long chamber and side-mounted heating elements for even temperature distribution, the HS-24K ensures optimal heat treating of longer blades or multiple knives in a single cycle—without hot or cold spots.
Built in Wisconsin with top-tier materials, this 240V knife heat treat oven heats up to 2200°F in just 35 minutes. It’s packed with standard features that other brands upcharge for: a solid state relay, cooling fans, audible alarm, and a door switch—all included. The cool-to-touch housing, removable door, and user-friendly controls make this oven ideal for home-based knife makers and professionals alike.
Add an Argon Gas Kit to minimize scaling and improve your blade finish. Whether you're tempering, hardening, or normalizing, the HS-24K offers everything you need for safe, precise, and efficient heat treating right in your own workshop.

The Perfect Oven For Knife Making
Heat treating knives is done to harden the steel for sufficient use and to not cause any damage or weakness to the knife. Owning your own oven allows you to heat treat on your time and not have to wait for the heat treating facility.
What is heat treating?
Heat treating can improve the strength, durability and reduce wear on material. It is the process of heating metal to a certain temperature, ramping the temperature(s) at a certain rate of time, soaking or holding it at the temperature(s) and then cooling it.
Why heat treat?
The purpose of heat treating is to bring steel to a hardened state. The correct hardness depends on the application of the steel being treated.
Why would I want my own oven to heat treat?
The main reason you would want to do your own heat treating is to save time and money. Heat treating facilities can often be backed up, expensive and require certain size batches of material to be done at one time. Heat treating knives allows the knife to get to a hardness level that will not cause the knife to bend, get damaged or cause any weak parts.
Constructed to last
Hotshot ovens are specifically designed with the end user in mind. Hot Shot ovens feature a full swing side opening door to allow safe and easy insertion and removal of material as well as a cool-to-touch one-handed handle made from high-quality stainless steel for easy opening and closing.
Hot Shot ovens are constructed with a high-quality powder coated shell. The high-density fiber insulation in a Hot Shot oven is machined to high tolerance specifications so that each piece fits perfectly together to provide a proper seal, ensuring that it will maintain its temperature and work efficiently to prevent loss of heat. Each oven comes with a removable high-density floor. This is ideal to assist with project setup or if it needs to be replaced.
Hot shot uses Kanthal A1 heating elements, a type K thermocouple and every oven comes standard with a solid state relay at no additional charge.
Advanced Features
Solid State Relay
Unlike many other ovens & kilns all Hot Shot ovens come standard with a solid state relay. Having a solid state relay eliminates the distractive clicking noise that a mechanical relay makes. A solid state relay is also more dependable and provides a longer life expectancy than that of a mechanical relay.
Programmable Alarm
Each unit comes standard with an integrated alarm that can be set to alert the user when a desired point or temperature is reached in the program.
Safety Door Switch
We also have integrated a safety door switch that will de-energize the heating
element when the door is open.
Argon Gas Inlet Flow Meter Kit (Optional)
Argon is usually delivered at dew point less than -75°F with an oxygen content below 20 ppm. This gas provides an inert atmosphere and is suitable for a variety of heat treatment processes.
Annealing (non-ferrous metals, stainless steel, and alloy steel)
Brazing
Sintering
Hot Shot offers this well-designed and easily adaptable Argon kit for all your heat-treating needs. Includes flow meter, tubing, fittings and ceramic dispensing needle.
(Argon gas not included)
