A Yanagiba knife is a traditional Japanese knife primarily used for slicing raw fish for sashimi and sushi. It features a long, thin, single-bevel blade that allows for ultra-clean, precise cuts. This design minimizes damage to delicate fish flesh, preserving both texture and flavor.
Highly valued by sushi chefs, the Yanagiba is known for its precision and performance. It’s also commonly referred to as a “sashimi knife” or shobu bocho, and is sometimes simply called “Yanagi.”
The Origins of the Yanagiba Knife
The word “Yanagi” translates to “willow blade” in Japanese, a reference to the knife’s long, slender shape resembling a willow leaf. This elegant tool originated in Osaka, a historic center for both sushi culture and Japanese knife-making.
The Yanagiba is deeply rooted in Japanese culinary craftsmanship, reflecting centuries of refinement in both technique and tool design and is an essential sushi knife.

Primary Uses of a Yanagiba Knife
While the Yanagiba is highly specialized kitchen tool, it excels in several key culinary tasks related to sushi making:
Slicing Sashimi
Its razor-sharp edge allows for clean, precise cuts without tearing the fish. This preserves the natural texture and enhances the visual presentation.
Sushi Preparation
Perfect for slicing fish in thin slices for nigiri and sushi rolls, ensuring consistent thickness and a professional finish.
Skinning Fish
The sharp, single-bevel edge makes it ideal for removing fish skin in a single, smooth pull.
Filleting
Suitable for small to medium-sized fish when using the traditional pull-slice technique.
Beyond Fish
Experienced chefs may use a Yanagiba to carve roasts or slice meat very thinly. However, it is not designed as a general-purpose knife.
