Q. Can you repair a knife that I bought at another shop?

Q. Do you offer honba-zuke (final edging) for new knives bought from other stores?

A. We offer complimentary final edging for Kamata Hakensha knives purchased at our shop while you wait. Please note that this service is not available for knives purchased elsewhere, even for a fee. Kamata Hakensha knives are ready to use, while knives from other manufacturers usually require more work, which incurs a fee.

Q. The handle of my knife is broken. Can you repair it?

A. We cannot repair Western knife handles, as they are attached with rivets and may require welding.
Handle inserts of Japanese knives can be replaced, but in some cases, repair may not be possible if the blade is severely rusted or corroded.

Q. How many days does it take to replace a handle?

A. In order to ensure durability, we have the handle replaced by a professional. This takes about 10 days.
