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，以價格親民、易於研磨以及出色的抗鏽性而備受好評。由於其均衡的特性，特別推薦給經驗較淺的使用者。添加鉬和釩之後，AUS-8的強度、硬度與耐用性都獲得提升，定位為中高階品質的鋼材。它與440鋼相當，但在硬度和抗鏽性上更為突出。適當的深冷處理能進一步改善其鋒利度保持性與韌性，使AUS-8成為刀具製造商與追求品質和性能的使用者心目中，兼具成本效益的選擇。
