Description

Hardened flat steel N690

Steel is vacuum hardened and tempered to a hardness of 60HRC. It can be used immediately for blade production and thus shorten the time of knife production, or catch some "burner"... Using already hardened steel also minimizes the risk of deformation of the finished blade and eliminates the need for straightening.

This steel is only suitable for belt grinder owners and cannot be drilled with conventional drills or machined with conventional hand tools! It is very hard!
