Steel rusts. There is no such thing as stainless or rust proof steel. The steel that we use is 154cm and it is a high carbon tool steel. It’s formula just qualifies it as a stainless class steel. Our steel, 154cm, will rust given the right or should I say, wrong circumstances.
The stonewashed finished knives are raw steel with no coating. That means there is no protective barrier between the steel and the environment.
We do offer black coated blades.
Why do some of the stonewashed blades show surface rust? Because they have been exposed to an environment conducive to rust. It’s really that simple. We wipe all of our blades down with Sentry Tuf Cloth prior to assembly to give them that measure of protection. However, after exposure to certain environmental conditions or after someone has wiped or cleaned off the Tuf Cloth solution, the steel is then exposed.
