Knife characteristics

Usuba is a traditional Japanese vegetable knife with a single-bevel edge, designed for exceptionally precise cutting, chopping and peeling of vegetables. The tall, rectangular blade enables stable work and creating thin, even slices. The knife is made from high-carbon steel, which ensures very high hardness and long edge retention, while requiring conscious maintenance. The simple wooden handle in wa style shifts the balance toward the blade and ensures full control over cutting.

High-carbon steel knife maintenance:

Always wash the knife by hand with lukewarm water and very mild detergent – do not put in the dishwasher.

Immediately after washing, thoroughly dry the blade with a soft cloth.

Store the knife in a dry place, preferably on a magnetic strip or in a saya/sheath.

Periodically (especially during longer periods of non-use) protect the blade with a thin layer of camellia or mineral oil.

Sharpen only on Japanese whetstones – recommended grit: #1000 / #3000.

**Natural patina (discoloration) is a normal phenomenon and protects the blade from corrosion – it should not be removed aggressively.
