To replace a handle

The cost of replacing a handle varies depending on the type and size of the knife. The Japanese style handle can be replaced the same day it arrives. It would take time and cost extra (more) to replace the knife if the tang (nakago) rusts badly. Although a handle is normally replaced to fit the size of the knife, the other kind of handle can be replaced as the customer requires. For the western style knife, it takes about a month to replace the handle by the expert craftsman. We recommend to replace a handle before it is damaged badly. If you continue using a knife that has diminished in size from years of sharpening or whose handle cracks due to rusted tang (nakago) and it becomes brittle and might be broken during use. We recommend that the handle of the knife should be replaced new one before the damage becomes worse.
