黑打 鎚目

黑打鎚目結合了粗獷自然的黑色表面與極具個性的鎚目紋理。這種處理方式相當常見，因為黑打工藝會在鍛造後保留鋼胚原始的黑色氧化皮而不進行拋光，同時也會保留鍛造過程所形成的質感，讓刀身得以呈現各式各樣的紋路與凹凸痕跡。作為黑打與鎚目的結合體，這種表面處理也繼承了兩者的優點：減少切割阻力、提升食材離刀性，並保護鋼材免受鏽蝕。整體而言，黑打鎚目是一種兼具實用性與獨特美學的表面處理工藝。

This finish layers the two traditional techniques: forge scale (kurouchi) is preserved across most of the blade, and hammered marks (tsuchime) are added on top. The result is a deeply textured rustic appearance with both the black forge layer and the dimensional hammer indents.

This combined finish appears on rustic, artisan-forged Japanese knives from regional blacksmiths — typically carbon-steel gyuto, santoku, and bunka — where both traditional techniques are deliberately preserved for aesthetic and functional reasons.

Combine the care of both finishes. Hand wash carefully around the textured/forge-scale zone, dry immediately, oil between uses for carbon cores. Avoid abrasive pads or strong detergents which will damage the kurouchi layer. The hammered indents may trap residue — brush gently under running water.
