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.

瑞典鋼是一個廣泛的術語，用於指由兩家主要瑞典鋼鐵公司——山特維克（Sandvik）和烏德霍爾姆（Uddeholm）——生產的幾種不同類型的鋼材。出於某些未知原因，日本刀具製造商似乎傾向於直接使用「瑞典鋼」這一稱呼，而非公開其具體鋼種細節。然而，以下幾種鋼材常被用於刀具製造：
烏德霍爾姆：AEB-L
山特維克：12C27、14C28、19C27
這些鋼材的碳含量相似（約0.6-0.7%），通常熱處理硬度達到HRC 59-60。
