About the steel : Bohler K720
Böhler Tool Steel K720 (O2) is a very tough and strong oil hardened high carbon tool steel. The focus of the steel is toughness and edge stability. The chemical composition allows it to be hardened to a high degree whilst maintaining ductility and toughness. This means the blade holds its edge for longer at the same time as it is resistant to chipping and cracking under heavy use. This steel also has a very fine structure making it easy to sharpen and achieve a razor sharp edge with. 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 if you want to avoid tarnish building up.
Steel analysis: C. 0.9%, Si. 0.25%, Mn. 2.0%, Cr. 0.35% V. 0.1% (HRC 58-60)
