For Left-Handed Customer

  • Left-handed blades must be special ordered from Japan, and will cost 50% more than the right-handed blades. Due to how each traditional Japanese knife is handmade by right handed craftsmen, it will take 4 to 6 weeks to forge and deliver.

Did you know?

  • Korin offers their customers a free maintenance service for all traditional Japanese knives!

  • The initial blade serves as a sharpening guide in the future. Free initial sharpening and uraoshi sharpening is available with every purchase. Please be aware that sharpened knives are not eligible for returns.

General knife care tips and warnings

  • Never wash knives in the dishwasher
  • This is not stain resistant. It will rust and discolor after cutting acidic ingredients or if one leaves it wet.
  • Improper care will result in chipping.
  • Please wipe knives dry after use to prevent rusting. Korin recommends wiping carbon knives with tsubaki oil to keep moisture off the knife.
  • Western style knives sold at KORIN have significantly thinner blades than typical Western knives. Use of honing steels or sharpening machines may result in chipping.
  • We advice all customers to always use sharpening stones to sharpen or hone knives.


Please be cautious when inspecting carbon knives with wet hands after purchase. We ask customers to inspect all knives prior to using, and will not accept returns on damaged goods. In the event you receive a rusted knife, please call customer service within 48 hours, and we will be happy to assist you.
