A Japanese term I like is "Shibui (渋い) ". Shibui is a certain esthetic beauty of soberness. This is also how I would discirbe our Saku series. It is subtle in design and looks. The stregth is in "Shibui (渋い), not in layered steel, tsuchime or mirror finish. The migaki finish is refined and delicate. Our SAKU series is constructed with a mono steel 1k6, a common kind of steel, normally hardened to a 58 Hrc, but our knifemaker manages a higher hardness. This way the steel becomes a better blade in practice for edge retention and sharpness.
