二唐VG10大馬士革槌目小刀150mm

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. It polishes well, offering an exquisite finish that highlights its subtle, elegant grain patterns. This wood is often used in fine woodworking projects, including luxury furniture, decorative items, and high-end knife handles.

An octagonal wa handle made from Black Chacate wood would exhibit a sleek, geometric shape that fits comfortably in the hand, enhancing the user's grip and control. The deep hues and natural luster of Black Chacate add a touch of sophistication and unparalleled beauty to the handle, making it not only a functional component of a kitchen knife but also a piece of art. The durability and stability of Black Chacate ensure that the handle withstands the rigors of kitchen use while maintaining its aesthetic appeal over time.
