Sleipner Knife Blank - S21
This blank arrives ground and hardened, which removes the two hardest steps from a knife build.
Uddeholm Sleipner is a cold-work tool steel with high chromium content, so it resists staining better than ordinary carbon steel while hardening to 60-62 HRC.
We buy steel direct from Voestalpine, grind each blade by hand on the belt grinder, and return the blanks to Voestalpine for heat treatment done to spec.
