Tosa Tsukasa 210mm Sujihiki. Iron clad shirogami 1 carbon steel blade, ho wood handle with horn ferrule.

The weights and measurements of free forged knives vary slightly.

Hand forged knives from the Tosa area of Shikoku Island, Japan's least populated island with a long history of smithing. Shikoku's thick forests, agriculture and fisheries have led to a local style of smithing that is characterized by rustic free forged knives and tools. Many Tosa knives are ryoba style; forged and ground symmetrically and are suitable for both right and left hand users. 

Please note, these can have cosmetic scratches or small imperfections in handles which will not impede the performance of the knife. This is par for the course on these knives and is part of how they sell them for a very reasonable price. We have been very happy with the quality for the price and their old style country feel.

This is a reactive carbon steel. It should be mentioned that extra care is required, as the knife is not stainless and should be dried immediately after use. It will develop a dark patina with usage, but any orange rust should be removed with a light abrasive.

Sujihiki

A sujihiki is a long, narrow Japanese slicing knife designed for clean, even cuts through cooked or raw proteins. Its thin blade reduces drag, allowing smooth, single-stroke slices that preserve texture and presentation. The pointed tip offers precision for trimming and detail work. Ideal for carving roasts, portioning fish, and producing uniform slices with minimal effort.

  • This is a 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.
  • 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

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.
