About This Original JIKKO design — a practical rework of the famous boning silhouette: deeper belly arc for long, clean pulls; fine tip for seam tracing; reinforced heel-side spine for leverage; control ring + contoured choil for a secure pinch grip. Triple-Layer Japanese SUS440A (~57 HRC) — multi-step heat treatment + 15° razor working edge for clean deboning and long-lasting sharpness without babying the blade. Black Titanium-Nitride Matte Finish — non-stick glide and added corrosion resistance for easier cleanup; the forged & hammered face helps reduce drag and sticking for smoother cuts. Handcrafted Handle — Olive wood & epoxy resin, individually hand-shaped; every pattern unique. Full-tang balance + control ring = precise, comfortable handling. Our most durable knife to date — built for the outdoors, refined for the kitchen: tough build for hard use, easy maintenance, and confident control in daily cooking.
