Custom assembled at Kakushin’s Knife Shop onto a water-resistant rubber handle, this boning knife was built with meat lovers and home butchers in mind. We wanted something that kept the character of a handmade blade while adding more durability and rust resistance for real-world kitchen and butcher work.
To make that happen, we commissioned a small custom batch forged in 440C stainless steel, finished with a striking copper San-Mai cladding that gives each blade a warm, almost molten appearance. The result feels both rugged and refined — a true working knife that still stands out visually.
At 160mm, the profile is ideal for trimming meat, cleaning cuts, removing fat, and working around soft tissue with precision and control. This is not a heavy bone-breaking butcher knife or a pry bar — it’s designed for finesse, clean movements, and accuracy. In return, you get a stainless steel core that handles moisture exceptionally well, stays cleaner longer, and still takes an impressively sharp edge.
The blade features a firm, no-flex construction with a smooth taper toward the tip, giving it a confident and predictable feel during detailed work. Every knife carries subtle handmade variations that make each one unique, while maintaining the consistency and performance expected from a serious working tool.
Low maintenance, durable, handmade, and ridiculously good looking — this limited batch brings together precision, character, and practicality in one purpose-built boning knife.
