ATS34 ATS-34
硬度
洛氏硬度(HRC) measures how resistant a steel is to permanent deformation. For kitchen knives:
55–58 HRC — Soft. Easy to sharpen and forgiving of rough use, but dulls faster. Typical of most German knives.
59–61 HRC — Balanced. Good edge retention with manageable sharpening. Common in mid-range Japanese knives.
62–64 HRC — Hard. Excellent edge retention, holds a very fine edge. Requires more care and a fine stone to sharpen.
65+ HRC — Very hard. Exceptional edge longevity but more brittle — more prone to chipping if used roughly.
Higher is not always better — it depends on how you use and maintain your knife.

The ATS-34 steel, manufacturerd by Hitachi Special Steel, is the Japanese equivalent of the 154CM, famous for its toughness, corrosion-resistance and "high-speed" properties.
The 154CM was originally designed for jet engine turbine use, however it found its fame in the knife world after legendary knife maker Bob Loveless started using them for his hunters. In the years after that, the 154CM / ATS34 was considered as the top of the line steel by many makers and is still considered so. The high-manganese alloys provides a favorable combination and balance of properties like ductility, formability, strain hardening, and strength.
