不鏽鋼
不鏽鋼
"Stainless" means stain-resistant, not stain-proof. In kitchen use, the steel can still discolour or pit if exposed to acidic environments — citrus, vinegar, or salt water — for extended periods. Wash and wipe dry after every use, and avoid leaving the blade soaking in water. With basic care, a stainless knife is very low-maintenance and a great everyday choice. Sandvik，瑞典 Uddeholm，瑞典

硬度
洛氏硬度(HRC) 衡量鋼材抵抗永久變形的能力。就廚刀而言：
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，用於指稱由兩家瑞典主要鋼鐵公司——Sandvik與Uddeholm——所製造的數種不同鋼材。由於某些未知原因，日本刀匠似乎傾向於僅使用「瑞典鋼」這個詞，而不公開其具體規格，然而以下鋼材經常被用於刀具製作：
Uddeholm：AEB-L
Sandvik：12C27、14C28、19C27
這些鋼種的碳含量相近（0.6-0.7），通常熱處理至約HRC 59-60。
