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.

AUS-8 常被稱為「鉬釩鋼」，是一種日本不鏽鋼，以其高性價比、易於研磨以及優異的耐腐蝕性而備受讚譽。由於其性能均衡，特別適合初學者使用。添加鉬和釩元素後，AUS-8 的強度、硬度和耐用性進一步提升，定位為中上級品質的鋼材。它與 440 鋼相當，但在硬度和耐腐蝕性方面表現更優。經過適當的深冷處理後，其保持鋒利的能力和韌性會進一步增強，使其成為追求品質與性能的刀具製造商及用戶的高性價比之選。
