In a discussion, Peter Monahan shares that there were US troops in India/Pakistan during WWII having first arrived in Karachi in 1942 and quite a number being stationed in Calcutta as part of the support for the India-China air route and the operations in Burma. This is probably how these American bayonets came into India as one was sourced from the North and the second from the North-East of India!
The AK series bayonets were actually multi-tools as has been well explained in this video: https://www.youtube.com/watch?v=gzEu3ettW6E
