With the introduction of the AK-47 rifle in 1947, the bayonet was a change of mind and subsequently issued in 1955. Most AK bayonets conform to four basic types: the AK47, AKM Type I, the AKM Type II, and the AK74. Among these four basic types are literally hundreds of variations and combinations.

These are just three that I own. From top to bottom:
- the AK47 knife bayonet
- the AKM Type I knife bayonet
