ABOUT THE STEEL:

O2 HIGH CARBON TOOL STEEL

Böhler Tool Steel K720 is a very tough and strong oil hardened high carbon tool steel. The chemical composition allows it to be hardened to a high degree whilst maintaining ductility and toughness at the same time as it is easy to sharpen and can obtain a razor sharp edge. Whilst easy to sharpen, the low chromium content means it will tarnish if left wet and it must therefore be wiped after use and protected by oil or wax when put away for storage. Steel analysis: C. 0.9%, Si. 0.25%, Mn. 2.0%, Cr. 0.35% V. 0.1% (HRC 58-60).
