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.

- As seen on Edible Brooklyn, November 2013

The Ginsan-ko embodies a new concept in Japanese knife making. A stain-resistant steel core is encased in a soft iron jacket to which 13% chromium has been added. Traditional methods of craftsmanship are combined with modern metallurgical advances to produce a true Japanese knife that has both an exacting sharpness as well as strong rust-resistance.

General knife care tips and warnings

  • Never wash knives in the dishwasher
  • Stain-resistant knives are not stainless.
  • Improper care will result in rusting and chipping.
  • Please wipe knives dry after use to prevent rusting.
  • 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.
