Trade in petty in great condition without original packaging. This stainless clad carbon knife shows wear only in some surface scratches in the kireba bevel that are consistent with use on a honing rod. The core steel has oxidized as expected with use and was mostly left in place prior to listing to give the new owner a head start on the patina development. Comes with a fresh BC edge.

  • 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

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.
