Overview
A micro-carbide powder steel hardened by ice forms the cutting heart of this Miyabi gyutoh, wrapped in layers of Damascus steel and finished with a D-shaped maple handle dyed black.
Reason to buy is the hardness and craftsmanship: ice hardened powder steel, sharpening by the traditional Honbazuke method and handcrafting in Seki. The limitation is that the listing gives no edge angle, so sharpening and thin blade handling are left to the owner.
Who it's for
Enthusiasts who treat a chef knife as a tool worth caring for will notice the thin profile and hand sharpening. Cooks who chop through bone should choose a tougher blade.
Pros and cons
- Very hard micro-carbide steel
- Flower Damascus layered finish
- Thin Japanese profile
- D-shaped maple handle
- Edge angle not listed
- Thin, hard blade needs careful use
- Single knife, no sheath listed
Performance notes
Ice hardening pushes the steel to a very high Rockwell rating, which supports edge retention and corrosion resistance. The thin profile cuts with little wedging, and the layers wrapped around the core give the blade its flower Damascus pattern. Honbazuke sharpening sets the initial edge in three steps.
