Harmonic Treatment
After 25 years of using heat to temper steel, I learned that heat only tempers the outer third of the steel. This is why the sharpening of an edge doesn’t last as long with each sharpening. I discovered a new way of tempering the steel all to its core, thus improving its edge by 300%. This method is the harmonic treatment and it is an innovative, patented metal treatment that uses sound waves to reach the steel's core.
