Fundamentally different from Western knife work. Single-bevel blades use a pulling motion that draws through the ingredient. A single-bevel blade creates a cleaner cut with less cell damage — critical for sashimi where the texture of the cut surface directly affects how fish feels in the mouth.
The pulling cut draws the blade toward you in a single smooth stroke using the full blade length. The weight of the knife does the work. Each cut is one motion. For sashimi, angle and direction relative to muscle grain determines texture. Katsuramuki (continuous rotary peeling of daikon into paper-thin sheet) is the foundational skill test. Three essential knives: yanagiba (sashimi), deba (fish breakdown), usuba (vegetables).
A yanagiba is the single most impactful Japanese knife addition to a Western kitchen. Keep it sharp on 1000/3000 grit whetstone. For sashimi, let fish come to slightly below room temperature. Cut with confidence in a single stroke — hesitant multi-pass cuts damage cells the same as a dull knife.
Sawing or rocking motion — fights the blade geometry. Pressing down instead of pulling through. Not maintaining the edge with asymmetric whetstone sharpening. Using on hard surfaces (glass, marble) — thin steel chips. Treating sashimi cutting as optional.
