AUS-8
Hardness
Rockwell C Hardness (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，又常被稱為「鉬釩鋼」，是一種日本不鏽鋼，以其高性價比、易於研磨及優異的耐腐蝕性而受到好評。由於其特性均衡，非常適合經驗較少的用戶。鉬與釩的添加提升了AUS-8的強度、硬度及耐用度，使其成為中高階品質鋼材。AUS-8與440鋼相近，但硬度與耐腐蝕性更佳。經適當低溫處理後，其持刃性與韌性更佳，對於追求品質與效能的刀具製造商與用戶來說，AUS-8是具成本效益的選擇。
