Tosa Tadayoshi 165mm Nakiri. Aogami 1 steel with iron cladding. Walnut D shaped handle with plastic ferrule

Free forged knives vary slightly in weights and measurements, expect small imperfections in finish or small amounts of wavyness in blade or roughness in finish.

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.

These knives come from the maker with lacquer on the blade for corrosion protection during shipping. It can be removed using acetone or lacquer thinner (follow manufacturers instructions for use).

We can remove the lacquer prior to shipping for an additional charge. Please add the suggested “Lacquer Removal” to your cart and proceed with checkout. Please note that lacquer removal can delay your order by up to one week.

  • 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.
