Forge Precision with the Hot Shot Knife Makers Kiln - HS18K
The Hot Shot HS-18K is designed alongside blacksmiths and knife makers to bring you precision, safety, and reliability in one compact unit. With its 18″ deep chamber, Cool-Touch exterior, and side-mounted heating elements, you can heat treat blades evenly from tip to tang while keeping your shop safe.
Built for hobbyists and professionals alike, the HS-18K eliminates the hassle of outsourcing your heat treating. Its even heat distribution, full swing door design, and intuitive controls let you work smarter and faster — whether you’re perfecting one knife or processing several.
The 120V model reaches 2000°F in 50 minutes (2200°F in 1 hour 40 minutes), while the 240V version achieves 2200°F in just 30 minutes. Add an optional Argon Gas Kit to prevent surface scaling and keep your blades pristine.
