Cafer is a Turkish artist known for combining stabilized natural wood, translucent epoxy, metallic accents, layered color, and sculptural detail into one-of-a-kind wa handles. Each handle has its own personality, from soft natural burl patterns to dramatic resin landscapes, skulls, ocean tones, gold flecks, and abstract art effects.\nThese are not basic replacement handles. They are statement pieces designed for high-end Japanese knives, custom builds, and collectors who want a blade that looks as special as it performs. A Prisma handle can completely change the character of a gyuto, sujihiki, kiritsuke, nakiri, or other larger Japanese knife by adding color, depth, balance, and a luxury custom look.\nFit and Sizing Guidance\nMost of these Prisma wa handles are best suited for larger Japanese knives. A 135mm handle is a very good general length for 210mm gyuto knives and larger blades, while longer handles may be better suited for 240mm, 270mm, and oversized knives depending on the blade weight, tang size, balance point, and customer preference. Because handmade Japanese knives and custom handles can vary, exact fit is never guaranteed without checking the specific blade.\nIf you are unsure whether one of these handles will fit your knife, please contact us before ordering. The Tokushu Knife team can help confirm whether the handle size, tang opening, and overall proportions are a good match for your blade. For customers purchasing a knife and handle together, we can also help advise on pairing the right handle style with the right blade.\nWhy Choose a Prisma Knife Handle?\nA custom Prisma handle gives your knife a true collector-grade presentation. The layered epoxy creates depth and light movement, while the natural wood keeps each piece grounded in traditional knife craft.
