Pchak – the national Uzbek knife, has a straight wide blade made of carbon steel wedge-shaped section with one-sided sharpening. The pewter guard (the knife element between the handle and the blade) is engraved. It has an attractive appearance, high resistance to external influences and high wear resistance. 52100 – structural bearing steel. Quite popular in the bladed environment in Russia and the CIS.
