二枚合 - 不鏽鋼夾層

「二枚（Nimai）」是日本傳統的廚刀製作工藝，這種結構常見於源自日本本土的刀型，如柳刃、出刃與薄刃。在打造二枚結構的廚刀時，會將一層軟質包覆金屬貼合於芯鋼之上，再將這兩片金屬鍛接並塑形成刀身。Nimai 刀具通常採用單刃方式研磨，在平面或內凹研磨面露出經過硬化的芯鋼，而軟質包覆層則覆蓋於另一側及刀脊。軟質包覆層為硬度較高但相對較脆的芯鋼提供支撐，使刀具既能擁有纖薄鋒利的刀刃，又具備整體強度。由於單刃日式刀具通常沒有第二刃面，軟質包覆層與內凹研磨的搭配，使得研磨過程比單一鋼材與本燒刀具更為輕鬆。近年來，刀具製造商嘗試將不鏽鋼夾層應用於傳統的二枚結構刀具上，這類刀具過去通常以碳鋼鍛造而成。然而，與三枚結構不同，即使不鏽鋼夾層能保護其中一面，芯鋼在凹磨面仍會外露。目前市面上可見的不鏽鋼夾層...

The 二枚合 - 不鏽鋼夾層 construction is produced through a specific combination of forging, lamination, and grinding processes characteristic of traditional Japanese knife-making. See the description above for details specific to this construction.

Hand wash with warm water and mild detergent, dry immediately with a soft cloth. Avoid the dishwasher, abrasive scouring pads, and prolonged contact with acidic foods. Carbon-steel knives benefit from a thin coat of food-safe camellia or mineral oil between uses.
