      Product Care Instructions

      HOW TO USE?

      • Only cut food you can bite and chew with this knife since hard foods can chip the blade. Do not cut olive pits, bones, lobster shells, wood pieces or frozen food, which are especially bad  due to the cold making hard steel more brittle.
      • Do not use the knife in twisting motions.
      • Use wood or plastic cutting boards to avoid dull knives. Do not use glass,  granite or bamboo surfaces.

      HOW TO CLEAN?

      • After each use, hand wash the knife with mild detergent and a soft sponge, rinse with hot water and dry by hand immediately. Do not use the dishwasher.
      • Wood handles may dry out over time and exposure to water. To prevent this, use some food safe mineral oil or beeswax.  

      HOW TO SHARPEN?

      • Use the FREE WHETSONE included with the knife for sharpening. It is recommended by the manufacturer.
      • Remember to sharpen both sides evenly as this is a double-bevel knife.

      HOW TO STORE?

      • Wrap the blade in newspaper to reduce direct exposure to the air and prevent rusting if you keep knives in a drawer or travel case. 
      • If you are hanging the knife or using a knife stand, remember that the blade should point downwards.
      • If you are storing them in a drawer, keep the edge from touching anything else.

      About this artisan

      Portrait of Shiro Kunimitsu master artisan

      Shiro Kunimitsu

      For over 200 years, the Shirou Kunimitsu clan has passed down their traditions and techniques in crafting Japanese swords in the countryside of Omuta city, in Fukuoka prefecture.

      Today, there are three craftsmen from the original family working together at the workshop: Yasumitsu, Kunimitsu, Kokuten.

      They use their ancestors' wisdom to not only create katana swords, but also traditional hand-forged knives crafted with the same steel and techniques as swords.

      The Shirou Kunimitsu clan is devoting themselves to inheriting and protecting sword making skills, carrying them to the next generation in the form of household and kitchen knives with unparalleled sharpness and performance.
