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.

瑞典鋼是一個統稱，泛指由兩家瑞典主要鋼鐵公司 Sandvik 與 Uddeholm 所生產的多種鋼材。不知何故，日本刀具製造商似乎習慣僅以「瑞典鋼」稱之，而未公開具體的鋼材型號；不過在製刀領域中，經常使用的鋼材如下：
Uddeholm：AEB-L
Sandvik：12C27、14C28、19C27
這些鋼材的碳含量相近（0.6-0.7），熱處理後的硬度通常落在 HRC 59-60 左右。
