READ IMPORTANT DELIVERY OPTION INFORMATION

SLD semi-stainless steel core clad with polished subtle geometric hammer marked stainless steel. Heat treatment offers a nice combination of edge life, and easy sharpening and toughness. SLD cuts well as it dulls and maintains a toothy edge for a long time. While not 100% stainless, SLD rusts very slowly and can be maintained almost as easily as stainless without intersecting with reactive ingredients like carbon steel. Avoid bones, pits and twisting knife on hard cutting boards.

Bunka

A bunka is a Japanese multipurpose kitchen knife known for its angular kiritsuke-style tip. Its flat edge profile excels at push-cutting and chopping, while the sharp, pointed tip provides precision for detail work and piercing tasks. Versatile and agile, the bunka covers everyday prep from vegetables to proteins with a bit more tip control than a standard santoku.

  • This is a semi-stainless steel knife made from thin, hard steel.
  • Semi-stainless steel knives can vary in corrosion resistance and can develop a light patina if they are neglected regularly.
  • Hand wash and dry immediately after use. Do not air dry or clean in the dishwasher.
  • Rust can form with repetitive long-exposure to moisture or debris. Remove surface rust gently with a mild abrasive and progress to more aggressive abrasives if needed. Coarse abrasives will leave scratches in most finishes.
  • Avoid twisting, scraping, or use on dense or hard foods and surfaces to avoid early dulling and edge damage. If you wouldn't bite into it, don't cut it with this knife.
  • Use on wooden cutting boards only. Do not use bamboo, plastic, stone or metal cutting surfaces.

Medium-Fine finish - Japanese

We recommend sharpening by hand using whetstones starting around 1000 grit progressing to at least 4000 for this steel type and edge geometry. Finish with a monodiachrome strop for a smooth cut with a substantial bite. Finer finishes are possible, but the knife may slide on smooth foods and overall edge retention may suffer. During repair, use a super coarse stone to pass chips quickly to help keep flat bevels.

  • Avoid pull-through sharpeners and non-water-cooled mechanized systems.
  • Strops and ceramic honing rods are preferred for as-needed edge maintenance. If you have to use a honing rod to be able to use the knife comfortably, it's time to sharpen the knife.
