7x7x9 Salt Bath Heat Treating Oven for Folder Knife Makers and Short Blades
The Evenheat Salt Bath 709 is designed with the folder knife maker in mind, offering a compact 9″ depth for shorter blades and steels. Its 7″ × 7″ × 9″ chamber accommodates salt pots up to 5.5″ OD (~16″ depth), making it ideal for pocket knives, small tools, and precision parts.
Reaching 2000°F (1093°C), the SB 709 provides fast, even heat transfer directly into the steel. This minimizes scale and decarb compared to air or atmosphere firing, resulting in cleaner hardening, consistent tempering, and reduced post-treat cleanup.
Running on a standard 120V, 18A circuit, the 709 is highly accessible while still delivering professional results. Whether in a home shop or a dedicated knife studio, it ensures reliable, repeatable performance in a compact footprint.
