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.

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.

堺孝行 INOX不鏽鋼系列採用不鏽鋼（「Inox」一詞源自法語 inoxydable），旨在提供性能、耐用度與低保養需求之間的實用平衡。此系列硬度通常約為 57–59 HRC，不僅能磨出鋒利刀刃，研磨過程也相當輕鬆，相較於硬度較高且質地較脆的鋼材更具容錯性。其不鏽鋼材質具備優異的防鏽與抗污能力，非常適合不希望像使用傳統碳鋼那樣費心保養的使用者。雖然其鋒利持久度屬中等水準，或許無法媲美高階碳鋼或粉末鋼，但 INOX不鏽鋼系列在日常廚房使用中表現卓越，尤其適合追求穩定可靠且易於保養的家庭料理人與專業廚師。
