Masamoto KK Kasumi Kamagata Usuba 210mm (8.3")

Vegetable Knife

Masamoto KK Line

Masamoto’s White Steel Kasumi is a 100% hand forged line. The blades are forged by joining white steel with a soft carbon jacket and each blade is hand hammered, shaped, tempered and cooled by Masamoto’s expert craftsmen. After the blacksmith has completed his work, a dedicated edge crafter puts on each edge by hand using a combination of wheels and stones. The result is precision cutting and incredible sharpness.

*These knives are single edged and are for right handed users. Please contact us at for pricing on left handed models.

Use & Care

  • Handwash in warm water and towel dry

  • Carbon steel is not rust resistant and requires special care. Wipe your knife completely after use to prevent oxidization.
