Horizontal Electric Kilns

KF-13.5 model shown. Deeper models available, see below.



The KF Knife Ovens allow you to explore the process of heat treating. These ovens give the craftsman the freedom to decide how the blades are treated, the freedom to learn by hands-on, and the freedom to try new techniques. We think you will enjoy using an Evenheat Oven for your heat treating needs. We offer a range of chamber depths starting at 13.5" to 49.5".


All Evenheat Knife Ovens are available with three control options: Set-Pro, Rampmaster III or TAP. There are a couple relay options as well. Please contact me with your requirements. I will be happy to work with you, to be sure you get what you need.

Shipping will be quoted on an individual basis. I will need your City, State and Zip Code for a shipping quote.
