Korin Knife Sharpening Service


Korin is the first company in the world that was given authorization and certification to re-sharpen and repair knives from Masamoto Sohonten, Misono, Knife Systems (Suisin) and Nenohi. Each knife sharpening from Korin will receive a complimentary plastic saya cover for the knife.


There are two ways to get your knives sharpen by Korin:

1

Drop off your knives at our
Korin showroom at
57 Warren street,
New York, NY 10007

or

2

Mail in your knives with the printed
knife service form to:
Korin Knife Service
57 Warren Street
New York, NY 10007


After we receive your knives in transit, it takes 2-3 days to process your knives. Then our staff will ship out your knives. Knife Sharpening Form

Download the sharpening form linked in the red “Knife Sharpening Form” button above. Print, fill out the form and mail it with your knives. We sharpen all brands except for serrated and ceramic knives.

Please note that we are unable to sharpen/repair left handed traditional (single sided) knives not purchased from Korin. Left handed traditional knives purchased from Korin will be sent to Japan for repair.

Korin are able to clean rusted blades or clean discoloration knives. However, there will be some isolated cases where cleaning is not possible. Watch the following video where Vincent explains some examples of such cases:

Korin Knife Service

Wrap your knives up very carefully using several sheets of newspaper. Please DO NOT include blade covers, boxes, or sayas.

Please pack your knives in a shipping box with extra cushioning (bubble wrap and/or newspaper) and please DO NOT mail in in an padded envelope to avoid accidents during shipping transit.
