As light dances across the blade, vivid reflections burst from brilliant gold and fiery pink to electric blue, emerald green, and deep violet. The effect is bold, luxurious, and constantly changing—an unmistakable statement piece that looks different from every angle. It's one of those finishes that immediately stops people in their tracks.\u003cspan class=\"PDq2pG_selectionAnchor\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-end=\"1074\" data-start=\"557\"\u003eThis particular knife is truly one of one. While the blade itself comes from one of Hatsukokoro's most striking series, we transformed it into something entirely unique by hand-assembling it here at Kakushin with a custom full-tang handle crafted from mesmerizing blue swirl stabilized epoxy. The flowing shades of blue perfectly complement the rainbow Damascus blade, creating a seamless fusion of modern artistry and traditional Japanese craftsmanship. Once assembled, no second knife like this will ever exist.\u003c\/p\u003e\n\u003cp data-end=\"1570\" data-start=\"1076\"\u003eAnother beautiful creation from Hatsukokoro, the blade is part of a collaborative project that brings together some of Japan's most talented blacksmiths, sharpeners, and craftsmen. By partnering with renowned artisans across the country, Hatsukokoro consistently delivers knives with exceptional fit and finish, outstanding cutting performance, and remarkable value. While unquestionably a premium knife, the level of craftsmanship and refinement often rivals pieces costing significantly more.\u003c\/p\u003e\n\u003cp data-end=\"1984\" data-start=\"1572\"\u003eHandcrafted in Echizen, this 170mm Bunka features an exclusive rainbow finish layered over a flowing Damascus pattern, giving the blade incredible depth beneath its vibrant colors. Every movement catches the light differently, revealing dramatic shifts between warm and cool tones that make the knife feel almost alive. It's a finish that confidently blends modern luxury with traditional Japanese craftsmanship.\u003c\/p\u003e\n\u003cp data-end=\"2448\" data-start=\"1986\"\u003ePerformance is every bit as impressive as its appearance. At its core lies premium SG2 (R2) powdered stainless steel, hardened to approximately 63 HRC, providing exceptional edge retention, impressive corrosion resistance, and long-lasting cutting performance. The grind is unmistakably that of a true laser: incredibly thin behind the edge, effortless through ingredients, and designed to glide with minimal resistance while delivering remarkable precision.\u003c\/p\u003e\n\u003cp data-end=\"2870\" data-start=\"2450\"\u003eAt 170mm, the Bunka is one of the most versatile profiles available. Compact, agile, and incredibly easy to maneuver, it excels at everything from vegetables and herbs to boneless proteins and detailed prep work. Its signature reverse tanto tip offers exceptional precision for intricate cuts, while the taller blade provides generous knuckle clearance and plenty of surface area for scooping ingredients from the board.\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"3285\" data-start=\"2872\"\u003eThis isn't simply another premium Japanese knife—it's a one-of-one custom creation. Combining the effortless cutting performance of an SG2 laser, the breathtaking brilliance of Hatsukokoro's rainbow Damascus finish, and a custom blue swirl epoxy handle assembled by hand at Kakushin, it stands as both an elite kitchen tool and a true collector's piece. Once it's gone, there won't be another exactly like it.\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Assembled in Canada 🍁","offers":[{"title":"Default Title","offer_id":51586487681257,"sku":null,"price":500.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0261\/4368\/6711\/files\/Rainbow_Bunka.png?v=1785101792","url":"https:\/\/kakushin.ca\/fr\/products\/ryuhyo-rainbow-r2-sg2-custom-161-damascus-bunka-170mm","provider":"Kakushin","version":"1.0","type":"link"}
