READ IMPORTANT DELIVERY OPTION INFORMATION

Hand made in Sakai, finish stainless clad shirogami 1 forged by dentoukougeishi master smith Kenji Togashi and expertly ground by his son. Stainless clad shirogami 1 is a less common combination as it is more challenging to work but it offers a great combination of the shirogami 1 carbon steel's fine edge formation and long edge life with the stainless steel's ease of use.

These are super easy to sharpen with a great cutting duration and smooth cutting feel with nicely finished corners. Slightly larger than usual geometry for a Sakai gyuto but still following in that style.

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.

Handle Material:

  • This is a stainless clad carbon steel knife made from thin, hard steel
  • Hand wash and towel dry after use. Do not air dry or place in the dishwasher.
  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.
  • The carbon steel edge will oxidize with use and may rust if left wet. The stainless clad outer layers resist corrosion but can still stain with prolonged moisture exposure.
  • 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.

Shirogami 1 (White Paper #1)

Carbon (C): 1.25–1.35% | Manganese (Mn): 0.2–0.3% | Phosphorus (P/S): trace

Shirogami 1 is an ultra-pure high-carbon steel (~1.25–1.35% C) from Hitachi, delivering extreme sharpness and easy honing. Capable of ~65 HRC, it’s used for razors and fine kitchen knives. Its low impurity content yields an exceptionally fine grain but requires vigilant maintenance to prevent rust.
