The Shirasagi series is made in Tosa, Japan by Blacksmith Tamura Toru of Testusjin Hamono using Ni-Mai technique. These single bevel knives are sharpened by single-bevel specialist Myojin Tateo, son of Myojin Naohito.

Ni-mai is a specialized double forging technique that applies soft cladding only to the cutting side of the knife. This technique is not common to the Tosa region.

Shirogami gets phenomenally sharp more easily than many other steels that are alloyed for longer edge life, while it is not pre-engineered for edge life, it is a sharpeners dream steel. It is a blank canvas for experimenting with different finishing stones. 

Shirogami is a reactive carbon steel. It should be dried immediately after use to avoid rusting. It will patina with normal use. No soaking or dishwasher. Rust can be removed with a light abrasive.
