What to Do If a Japanese Knife Chips
Sep 27, 2026
A small chip in a Japanese knife is often repairable, but the correct response depends on the size and location of the damage. Do not keep forcing the damaged section through hard food, and do not grind only at the chip until the edge becomes uneven.
Why Japanese knives can chip
Thin edges and relatively hard steels can cut very well but are less tolerant of twisting, prying, frozen food, heavy bone and very hard cutting surfaces. Chipping can also happen after a drop or impact.
Very small chips
Minor microchips can often disappear gradually through normal sharpening as the entire edge is maintained evenly.
Larger chips
A visible chip may require a coarser stone and controlled reprofiling of the whole affected section. Removing enough steel to reach the bottom of the chip changes the geometry, so large repairs should be done deliberately.
Broken tips
A broken tip is repairable in many cases, but reshaping from the spine or edge changes the knife profile. Professional repair is sensible when the missing section is substantial.
When to use a professional
Use a specialist for deep chips, several chips across the edge, a damaged single-bevel knife, valuable finishes, major tip loss or any repair where you are unsure how much steel must be removed.
How to prevent another chip
- Do not twist a thin edge inside dense food.
- Avoid bones and frozen food unless the knife is designed for them.
- Use a suitable cutting board.
- Store the edge so it cannot strike other metal objects.
