Tinted rows are where these two differ.

The steel difference

CPM-20CV

Crucible's answer to M390 and chemically near-identical to it. Superb edge retention and corrosion resistance, slow to sharpen.

Bohler M390

The steel that defined the premium tier. Mirror-capable, extremely wear resistant, and unhappy about lateral loads.
