Messermeister Mu Micarta 7" Usuba Knife - MU-108
The Usuba is a broad bladed single edge blade with a distinctively curved tip or a blunt tip and looks like a vegetable cleaver. The usual blade length is 180 mm. It is traditionally used like a paring knife by holding it in the air and cutting the item being held by the other hand.
The single edge blade is used mainly to cut vegetables such as daikon and cucumber into paper thin slices, and it is so sharp it can thinly peel in a continuous strip (katsura-muki) a Tsuma, a Japanese radish which is served with sashimi.
