Ji Series Bunka Knife – Tricolour Copper Damascus Steel | Precision and Artistry Combined
The Ji Series Bunka Knife represents the perfect fusion between precision engineering and traditional Japanese-inspired craftsmanship.
Its blade is forged from 53 layers of Tricolour Copper Damascus Steel, composed of 316L stainless steel, brass, and purple copper, intricately interwoven to produce a unique pattern that enhances both durability and corrosion resistance.
At its core lies 12Cr18MoV steel, a refined alloy formulated for exceptional hardness, edge retention, and structural balance — achieving a Rockwell hardness of 60 ± 2 HRC.
The edge is hand-sharpened to a 15° ± 1° per side angle, ensuring ultra-precise, razor-sharp performance suitable for professional kitchen tasks.
The integral rounded transition from heel to spine reduces pressure on the fingers, providing superior comfort during extended use.
Its ergonomic handle, crafted from premium Padauk burl wood combined with cupronickel and black G10, offers natural grip, stability, and a refined tactile feel.
Designed by Steve Zheng, this knife embodies both form and function — a refined tool for chefs and enthusiasts who demand excellence in every slice. Ideal for cutting, slicing, and shredding vegetables, fruits, and soft-textured foods with unmatched precision.
