Traditional left-handed knife sharpening will be delayed for approximately 4 weeks. We apologize for any inconvenience this may cause.
Having trouble sharpening your knives? Do your knives have chips in them? Do you need an extra-sharp edge for a special event? Send in your knives to Korin for a tune-up. We can sharpen and repair virtually any non-serrated knives, including hunting, and pocket knives. We sharpen all knives by hand using a variety of Japanese water stones. Prices vary from styles of knives and severity in damages. Traditional knives such as yanagi, usuba, and deba, require more labor and skill, thus will cost more to sharpen.
Korin is the first company in the world that was given authorization and certification to re-sharpen and repair knives from Masamoto Shohonten, Misono, Knife Systems (Suisin) and Nenohi.
Knife Sharpening and Fixing Fee
* Even if the knife company is a Japanese brand, it may not be a Traditional Japanese Style. Please note, Korin will determine price by the style. * Completion of services are guaranteed within 7 days not including shipping time.
If you crack or chip your blade, send it to us for repair. We use specialized mechanical water wheels imported from Japan. All knives are hand finished on water stones. Prices vary according to the type of knife and amount of repair work necessary.
* Our knife sharpening and repair services are available for any knives regardless of where they are purchased or if we carry them.
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: Watch video
