Evenheat 45" Knife Oven with Greater Depth for Large Blade Work
The Evenheat KF Extreme 45 Knife Kiln gives you one of the longest chambers available, measuring a full 45". This size is ideal for large blades, swords, and specialty tools that require extra room to heat treat properly. You can also batch smaller knives together, saving time while keeping your results consistent.
Firing up to 2200°F, the KF Extreme 45 handles stainless, carbon, and tool steels with precision. Its digital controls make it easy to set soak times, ramp rates, and cooling cycles for repeatable hardness and finish. That means your blades come out evenly treated, reducing stress during the quench.
This kiln is designed with safety and comfort in mind. Dual side-opening doors make loading long pieces simple, while stainless door shields and cool-touch handles keep your hands safe. Whether you’re tackling oversized projects or producing regular runs, the KF Extreme 45 provides the control and reliability you need.
