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鋼是一款頂級粉末冶金不鏽鋼，以其卓越的硬度與出色的鋒利保持度聞名。由日立金屬開發，其高碳與鉻含量極高，使硬度可達 67 HRC，堪稱製刀領域中最堅硬的鋼材之一。正因為擁有如此驚人的硬度，ZDP189鋼能研磨出極為細緻的刃口，並在長時間高強度使用下依然維持銳利，其鋒利保持度遠勝許多其他鋼種。不過，高硬度也意味著研磨難度較高，若使用不當則較容易崩刃。儘管 ZDP189鋼因含有大量鉻而具備一定的抗腐蝕能力，日常仍需細心保養刀身。憑藉這些優異特性，ZDP189鋼常見於高端與特規刀具，深受重視切削性能與耐用度的玩家及專業人士青睞。
