We do not accept repairs for chips only. Since we will also resharpen the knife when repairing chips, you will be required to pay the chip repair fee in addition to the regular resharpening fee. Click here for repair fees depending on the size of the chip.
Example: A Santoku knife with a 5cm chip
Re-sharpening fee [Santoku knife] ¥1,400 + chip repair [5mm] ¥200, totaling ¥1,600.
We have rotating water whetstones at our store, so we can thoroughly remove rust. However, if the rust has penetrated deeply, small chips may remain on the cutting edge.
Japanese-style handles made of natural wood can be replaced. However, if the inner part of the handle (core) is damaged or rusted, it may be difficult to replace, so please contact us so we can determine the condition.
*Please note that the Western-style handle, which is made of packerb wood with a bolster, cannot be replaced.
