Forge Your Edge with the 13x13x13 - 1.37 Cubic Ft. Knife Oven
The Evenheat HT-1 Heat Treat Oven gives you steady, even heat for precise blade hardening, small tool making, and specialty metal work. Its 13.5" x 13" x 13.5" chamber easily handles chef knives, hunting blades, punches, and chisels — giving you enough room for batch runs or longer pieces without crowding.
Firing up to 2000°F on a reliable 240V, single-phase setup, the HT-1 holds temperature with consistency that protects your work from warping or uneven hardening. You’ll get clean, repeatable results every time — whether you’re doing stainless steel, high-carbon, or specialty alloys.
Built for daily use in pro shops and serious home setups, this oven’s firebrick construction stores heat for smooth, controlled cooling. That means less guesswork, more accuracy, and better finished pieces straight from the oven to your quench.
