Description
Long Yi Chang 185mm Deba Bocho Knife - Yasuki Yellow Paper 2 Single Bevel Fish Head Knife
Product Overview

The Long Yi Chang Deba Bocho is a traditional Japanese single-bevel fish knife, forged from authentic Yasuki Yellow Paper #2= high-carbon steel.

Designed for professional fish butchery, it excels at breaking down whole fish, removing heads, and cutting through bones and cartilage—while preserving the delicate texture of sashimi-grade fish.

With a reinforced spine, hand-forged blade, and ergonomic octagonal handle, this knife balances raw cutting power with surgical precision, trusted by chefs and serious home cooks alike.

Key Features
Yasuki Yellow Paper #2 Steel Core
  • Steel Type: Hitachi Yasuki Yellow Paper #2 (Kinpaku #2) high-carbon steel
  • Hardness: 62±2 HRC for exceptional edge retention
  • Advantage: Pure carbon composition enables ultra-sharp edges and easy resharpening—ideal for heavy-duty fish processing
Traditional Deba Geometry
  • Spine Thickness: ~7.6mm for bone-cutting strength
  • Single Bevel (Kataba 片刃): 15°±1° primary bevel ensures clean, controlled cuts without tearing fish flesh
Hand-Forged & Hammered Finish
  • Tsuchime : Textured surface reduces drag and prevents fish skin from sticking
  • Hand Tapering: Removes machine marks, creating a smooth, efficient cutting stroke
Ergonomic Octagonal Handle
  • Material: Hackberry wood with black ox horn ferrule
  • Shape: Anti-slip octagonal profile for stability
  • Weight: Balanced weight (360g±5g) reduces wrist fatigue during extended butchery
The Long Yi Chang Difference

Every knife is handcrafted by artisans with decades of expertise:

  1. Forging & Lamination: Yellow Paper #2 core clad with low-carbon steel, hand-forged into the Deba shape
  2. Heat Treatment: Precise quenching and tempering for optimal hardness and toughness
  3. Hand Grinding & Polishing: Gradual thinning to single-bevel geometry with mirror-finish edge
  4. Final QC: Strict inspection ensures performance and safety standards
Care & Maintenance
  1. Hand wash only; avoid soaking
  2. Dry immediately and thoroughly
  3. Store in a dry, ventilated area; use a wooden sheath or knife block
  4. Sharpen with Japanese water stones (1000+ grit); avoid electric sharpeners
  5. Apply food-safe mineral oil periodically to prevent oxidation
