Nigara VG10 大馬士革 土目 Nakiri 165mm

三枚（Sanmai）結構是雙刃刀常見的製法，將兩片較軟的夾鋼鍛焊於較硬的鋼芯兩側。經過熱處理後，較硬但脆的鋼芯會形成鋒利的切刃，較軟的夾鋼則支撐鋼芯，提升刀身整體強度。

大馬士革三枚結構是以大馬士革鋼作為三枚夾鋼材料，為刀身增添美感。若核心為不鏽鋼，則大馬士革夾鋼也會是不鏽鋼，這樣能保護碳鋼或半不鏽鋼芯不易生鏽或變色。

軟夾鋼讓薄刃修磨比本燒或單鋼結構容易許多。但若夾鋼為大馬士革，無論是蝕刻、拋光還是鏡面拋光，修磨過程都會對夾鋼造成影響，因此大馬士革紋理不會像剛開箱時那樣。

The "Tsuchime" finish in Japanese kitchen knives refers to a distinctive hammered texture on the blade's surface. This traditional technique not only adds a unique aesthetic appeal but also provides practical benefits, such as reducing drag and preventing food from sticking to the blade during slicing. It's a hallmark of craftsmanship that blends functionality with artistry, making each knife not only a tool but a piece of art.

Black Chacate is a highly valued timber known for its deep, rich brown to almost black coloration, fine texture, and exceptional durability.
