浮刃

浮刃（浮き刃，意為「浮動的刀刃」）是一種極具特色的表面處理工藝。其刀身主體大多採用鏡面／拉絲處理，並在夾鋼線正上方透過噴砂工藝，施加一道霧面磨砂質感的飾帶。光亮的芯鋼與夾鋼上的霧面飾帶形成鮮明對比，進而突顯出刀刃的輪廓。由於夾鋼線通常呈現波浪狀起伏，使得刀刃彷彿懸浮於雲霧之上，這項工藝也因此得名浮刃。

An ukiba (浮き刃, "floating edge") finish is produced by polishing most of the blade to a migaki/brushed finish, then leaving a deliberate hazy band of unfinished or kasumi-style polish along the cutting edge area. The visual effect makes the cutting edge appear to "float" against the polished body of the blade.

Ukiba is a specialty finish found on premium Japanese kitchen knives where the maker wants to visually emphasize the cutting edge zone — often seen on higher-end gyuto, sujihiki, and slicer profiles from select makers.

The polished area requires migaki-style care (wipe to prevent water spots and fingerprints), while the hazy edge band is essentially a kasumi finish requiring only standard hand-wash-and-dry care. The contrast between the two zones may evolve subtly over years of sharpening.
