Maguro bocho knife is the ultimate cutting tool for chefs who work with whole tuna and large fish cuts. At Kiichin, we see growing interest from sushi chefs and serious home cooks looking for authentic Japanese tuna knives that deliver clean, precise slices without damaging delicate flesh.

1. What is Maguro bocho (tuna) knife?

A Maguro bocho knife is a traditional Japanese knife designed specifically for cutting tuna, especially large loins and whole fish. It features an extra-long blade that allows chefs to slice through wide surfaces in a single, smooth motion. This minimizes sawing and preserves the texture of the fish. The blade is usually single-bevel, which helps create ultra-clean cuts.

While tools like the Japanese fish knife are ideal for smaller fillets and everyday seafood prep, Maguro bocho knives are purpose-built for scale, control, and long draw cuts required when handling large tuna.

In practice, Maguro bocho knives are used for portioning tuna blocks, slicing sashimi, and breaking down large fish with precision. Their length makes them ideal for long pull cuts rather than chopping. These knives are commonly found in professional sushi kitchens and fish markets. For anyone handling tuna regularly, this knife becomes essential rather than optional.
