Bevel Type Analysis

KatabaFlat (Concave)Bevel Angle

Single Bevel (Kataba)

Traditional single-bevel (Kataba) blades are flat or slightly concave on the back (Urasuki) and beveled only on the front. This enables clean, razor-sharp surgical slices without pushing or squeezing foods—highly favored by Japanese sushi and sashimi chefs.

Yanagiba (Sashimi Slicer)

Yanagiba

Description

Yanagiba literally means 'willow leaf blade' because of its long, slender, and elegant shape. Originating in the Kansai (Osaka/Kyoto) region, it is the classic Japanese tool for slicing sashimi. Its long blade allows chefs to slice raw fish in a single, continuous pulling stroke, preventing cell damage and preserving the fish's raw flavor and glassy texture.

Blade Characteristics

  • Single-bevel (Kataba) with an extremely acute cutting angle.
  • Long, narrow blade, typically between 240mm and 360mm.
  • Slightly hollow-ground back (Urasuki) preventing food from adhering to the blade.
  • Very delicate and sharp tip for starting incisions.

Steel Recommendations

For this type of blade, professional makers typically suggest: Yasuki Blue Paper Steel (Aogami) or White Paper Steel (Shirogami) for ultimate push-cutting geometry and ease of hand whetstone sharpening.
