This knife's original model is DON-ZDP. The blade shape is "Tanto-Honzukuri" with Tanto-convex grind. Rockstead is making "Tanto" blade shape with their CHI model. But this blade shape is "Tanto-Shinogizukuri". That means straight grind.
There are only few knife makers who make this kind of blade shape. But nobody does a "Tanto-Honzukuri" with mirror polished surface.
The other point of the knife is the handle's design. This handle motif is traditional Japanese Tanto-sword (Wakizashi). Handle materials are ebony with silver plate inlays and decorated carp KOI menukis made by silver casting.
