Stainless chromium steel

Stainless chromium steel

The stainless steel used by Marttiini is a virtually care-free blade material.
A stainless steel blade remains sharp for long. 13% of the steel mixture is chromium, and the hardness of the mixture is 53–54 Rockwell units (HRC).
In some models, we also use high-carbon stainless steel with a HRC of 56-58.

A diamond sharpener is recommended for sharpening chromium steel.
