Tsunehisa White 1 不銹鋼包覆 Kasumi Gyuto 240 毫米黑檀木手柄

Chefs Knife

A Japanese chef's knife is known as a gyuto (牛刀 ぎゅうとう） gyūtō?), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

白鋼一號，也稱為白紙一號，在高端日本刀具材料領域以其卓越純度與性能脫穎而出。它是在白鋼二號基礎上進一步精煉並提高碳含量的進階版本。額外的碳含量讓白一擁有比前代更高的硬度（HRc），提升了其可研磨至極細刃口的能力。然而，碳含量的增加也讓鋼材變得稍微更脆。儘管如此，白一因其優異的持刃性與易於重磨的特性，深受專業廚師，特別是專精日本料理的廚師喜愛。與青鋼系列不同，白一不含鉻與鎢，專注於追求極致鋒利。這種特性雖帶來無與倫比的鋒利度，也讓其更易氧化，需細心保養，包括使用後立即擦拭與乾燥以防生鏽。
