銀三 / 銀紙三號 Silver #3 鋼
Hardness
Rockwell C Hardness (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.

銀三鋼，又稱為Silver 3或G3鋼，是一種用於高級廚刀的不鏽鋼。它因能夠提供傳統碳鋼的手感與鋒利度，同時具備不鏽鋼的抗腐蝕性而備受推崇。銀三鋼含有適量的碳、鉻及其他合金元素，因此在保刃性與易於研磨之間取得良好平衡。這種鋼材特別受到青睞，因其細緻的晶粒結構能造就極為鋒利的刃口，加上耐鏽的特性，使其成為專業廚師與家庭料理愛好者追求碳鋼表現卻又不想承擔保養難題的熱門選擇。銀三鋼廚刀以耐用、易於保養及優異的切割性能著稱，是尋求高品質不鏽鋼刀具人士的首選。
