PM / 粉末鋼
Powder Metallurgy (PM)
A modern steel-making process where the alloy is atomised into a fine powder and then compressed under high pressure before sintering. This creates an exceptionally uniform carbide distribution — far finer and more even than conventionally cast steel. The result is a blade that achieves higher hardness without sacrificing toughness, holds a keener edge for longer, and is more resistant to chipping. PM steels are generally considered a step up in performance, though they can be harder to sharpen on coarse stones. Hitachi Special Steel, Japan 🇯🇵

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.

ZDP189鋼是一種高端粉末冶金不鏽鋼，以其卓越的硬度和保持鋒利的能力而聞名。由日立金屬開發，其高碳和高鉻含量使其硬度可達67 HRC，成為刀具製造中最硬的鋼材之一。這種非凡的硬度意味著ZDP189可以磨出極其鋒利的刃口，並在大量使用後仍能保持鋒利，在保持鋒利度方面遠超許多其他鋼材。然而，其高硬度也意味著磨刀更具挑戰性，若使用不當可能更容易崩刃。ZDP189的高鉻含量也賦予它一定的耐腐蝕性，但仍需注意保養刀身。由於其優異品質，ZDP189常用於高端和專業刀具，吸引重視切割性能和耐用性的愛好者與專業人士。
