  • This is a carbon steel knife made from hard steel.
  • Carbon steel knives develop a dark patina and require attentive care.
  • Hand wash and dry immediately after use. Do not air dry or clean in the dishwasher.
  • Rust will form with long-exposure to moisture or debris. Remove surface rust gently with a mild abrasive and progress to more aggressive abrasives if needed. Coarse abrasives will leave scratches in most finishes.
  • New deba edges are thin. Avoid excessive twisting to avoid edge damage.
  • Do not use bamboo, plastic, stone or metal cutting surfaces.

Dive Deeper

Fine - Single Bevel

Sharpen on whetstones starting around 1000 grit for micro-bevel work or use a full progression from 400-6000/8000 when lowering the kireba. Don't over-sharpening the ura; only work long enough to flip the burr and polish. Do not use honing rods; instead, strop for burr removal and for as-needed edge maintenance with a borachrome (medium-fine finish) or chromium (fine finish).

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.
