This custom Shinka is another one-of-one creation assembled in-house at Kakushin, bringing together a traditional Japanese blade with a completely custom Western-style handle that transforms both the look and feel of the knife.
For this build, we selected a stunning block of premium Amboyna burl, shaping it into a rat-tang yo-handle. Renowned for its mesmerizing grain, rich golden-orange hues, and remarkable natural depth, Amboyna is one of the world's most sought-after burl woods. Every swirl, eye, and figure is entirely unique, making it the perfect match for a knife that will never be duplicated. The ergonomic Western profile offers a secure, familiar grip while showcasing the wood's incredible character from every angle.
At the heart of this piece is the Shinka blade itself. Hand-forged in Japan from Aogami Blue #2 carbon steel, it delivers the crisp, lively cutting feel that carbon steel enthusiasts love. Hardened to approximately 61 HRC, it strikes an excellent balance between edge retention, toughness, and ease of sharpening, rewarding the user with exceptional performance while remaining practical for everyday use.
The kurouchi finish preserves the blade's darker forged appearance, highlighting the texture and character left behind by the blacksmith's hammer and forge. Rustic yet refined, it proudly showcases its handmade origins while providing a timeless Japanese aesthetic that never goes out of style.
Forged for us in Tosa, Japan, by a fourth-generation workshop whose history dates back to 1920, the Shinka series reflects generations of craftsmanship evolving from traditional tool making into exceptional kitchen cutlery. Its thin geometry, smooth taper, and balanced profile make it an effortless performer through vegetables, herbs, proteins, and virtually any daily prep task.
This particular knife exists as one and only one. By pairing Shinka's beautifully traditional carbon steel blade with a handcrafted Western-style Amboyna burl handle assembled here at Kakushin, we've created a knife that feels every bit as special as it looks. It's a seamless blend of Japanese craftsmanship and custom artistry—a functional kitchen tool, a collector's piece, and a true 1-of-1 that can never be recreated once it finds its owner.
