Born for the big cut. “Maguro-Ken” takes its name from maguro — tuna — and ken — sword. This is K Romain’s answer to scale. A long, commanding blade inspired by traditional Japanese tuna swords, reimagined for the modern chef. Built to break down whole fish in clean, deliberate strokes. The extended length glides through flesh without sawing. The narrow profile keeps drag low and control high. Balanced for power, but tuned for precision when it matters. Handcrafted with K Romain’s signature finish, it carries Japanese purpose with French restraint. Not a novelty — a working blade for serious hands. For chefs who respect the ingredient and the craft.
