Fuguhiki knife has a blade profile that is similar to the Yanagiba, but it is narrower in height and is ground much thinner to enable it to cut extremely thin slices of Fugu (Blowfish).

The Fuguhiki was originally designed as a specialized knife for cutting slices of Fugu (Blowfish) in to extremely thin slices of Tessa (Blowfish Sashimi) using the Usuzukuri technique. Tessa is so thinly cut, that the pattern of the serving plate is perfectly visible through the slices, and they are often carefully arranged to accentuate the pattern of the plate.
