The knife bayonet (ШТЫК-НОЖ) is included into Russian equipment and arms upgrade kit called “Ratnik”. It is an AK-compatible bayonet designed by KAMPO, too. It is reportedly a very high-quality bayonet made of high strength steel with a titanium based coating. The wire cutting function is completely transferred to the sheath, which is a polymer made one. The sheath also stores a sharpener for the blade. The overall length of the Kampo bayonet is 11.4″ (290mm) with a blade length of 6.4″ (162mm).
