The upper part of the knife was made of leather, as a sort of a glove, designed to be worn with the thumb going through the hole, so that only the blade protruded from the hand. It was a curved, 12 cm long knife with the edge on its concave side. The knife was fastened to a bowed oval copper plate, while the plate was fastened to a thick leather bangle. The knife was fixed on the glove plate in order to prevent injuries and to prevent taking care of a separate knife in order to improve the work speed.
