Use & Care

  • Steel products are subject to rust. After each use, wash the knife well and wipe off water thoroughly with a dry cloth.
  • Too much sharpneing may cause cracks and less sharpness. Also, do not cut frozen ingredients.
  • For Masamoto knives, there is an approx. 5 mm gap between blade and handle for good functionality. Do not try to tuck it in; otherwise, the handle will crack.
