I recently found this knife/dagger, have no clue what type it is and what it was used for, there is a thumb hole I suspect on the spine as well as it looks to be “IMT” or “IMI” logo stamped on the side. It is also not very sharp at all I’m not sure because of intention or because of old age? Any ideas on what type of knife this is and what it could have been used for would help!
Thanks
