  • 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 - 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.

Aogami 1 (Blue Paper #1)

Carbon (C): 1.3–1.4%| Tungsten (W): 1.5–2.0%| Chromium (Cr): 0.3–0.5%

Aogami 1 is a high|carbon tool steel (~1.3–1.4% C) with tungsten and chromium additions that enhance hardness and wear resistance. It’s capable of ~65 HRC and maintains excellent edge retention with moderate toughness. The steel sharpens cleanly, forms an exceptionally fine edge, and is common in top|end Japanese kitchen knives. Like other Aogami steels, it rusts easily and requires attentive care.

About Tosa Tadayoshi

Tosa, Kōchi, Japan

Tosa Tadayoshi knives come from Kochi Prefecture, home to over 400 years of blacksmithing tradition. These blades reflect the region’s rustic, free-forged style—handmade with character and performance in mind. Often featuring kurouchi finishes and durable double bevels, they’re crafted by a small team using time-tested techniques. Tadayoshi knives offer a practical, approachable introduction to carbon steel, valued for their sharpness, durability, and the distinct individuality of each piece. They reflect Tosa’s no-frills, work-ready knife ethos, made for daily use with deep roots in Japan’s cutlery heritage.
