Evenheat 36" Knife Oven with Expanded Chamber for Bigger Blade Projects
The Evenheat KF Extreme 36 Knife Kiln gives you the chamber depth to heat treat longer blades, tools, and specialty steels with ease. With 36" of length, you can treat swords, chef knives, machetes, or multiple smaller blades in one firing, saving time while keeping your results consistent.
This kiln fires up to 2200°F, letting you work with stainless, carbon, or tool steels without worry. Paired with precise digital controls, you can dial in soak times, ramp rates, and cool-downs for repeatable results on every cycle. That means your blades harden evenly, with fewer surprises when it’s time to quench.
The KF Extreme 36 is built to handle daily use. Its firebrick interior holds heat evenly across the chamber, while dual side-opening doors with stainless shields protect both the kiln and your hands. Whether you’re building large projects or refining batches of smaller knives, this kiln keeps the process efficient, safe, and reliable.
