The blades maintain sharpness through triple-layer steel construction, ice-hardening and tempering, and a 12.5-degree edge that is mirror-polished by hand.
- The steel layers include a hard Cromova 18 Sanso stainless-steel alloy core.
- Ice-hardening and tempering increase hardness and help preserve the edge.
- The 12.5-degree edge is hand mirror-polished.
- Use honing steel when the knife starts to lose some of its original sharpness.
