Semi-stainless steels sit between carbon and full stainless. They will rust if left wet or neglected, but under normal use they tend to develop a patina — a dark, protective layer — rather than forming aggressive surface rust. Rinse and wipe dry after use and you will rarely have issues. Much more forgiving than true carbon steel, while still offering excellent cutting performance. 日立特殊鋼,日本
SKD SKD 合金工具鋼
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.
SKD 在鋒利度、食材脫離性及易磨性方面,表現與碳鋼極為相似,卻無需高度保養。因此,深受專業廚師喜愛。

SKD 元素組成
SKD 成分分析
SKD 含有什麼?
每種元素對刀鋼性能的貢獻。
| 元素 | 規格範圍 | 對刀的作用 |
|---|---|---|
| C碳 | 0.95–1.05% | The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance. |
| Cr鉻 | 4.5–5.5% | Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear. |
| Mo鉬 | 0.8–1.2% | Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat. |
| V釩 | 0.2–0.5% | Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge. |
| Mn錳 | 0.6–0.9% | Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness. |
| Si矽 | 0.4% | Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation. |
