  • This is a honyaki forged carbon steel knife.
  • Honyaki knives are made from a single piece of high-carbon steel and require particularly attentive care.
  • Hand wash immediately after use and dry thoroughly with a towel. Do not air dry or place in the dishwasher. The fine steel and hardened edge are prone to rust and chipping if mishandled.
  • Use only on wooden cutting boards and avoid hard, dense ingredients that could cause micro-chipping. If you wouldn't bite into it, don't cut it with this knife.
  • Twisting, scraping, or lateral force will damage the edge.

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).
