Today I found what I was told is a German ww1 fighting knife constructed from a Mauser bayonet blade and layers of what I think is plastic(could be smooth, hard wood I suppose), and metal of some sort.

There is also a bolt on the bottom that I assume holds it all together.

Also, around the guard where the blade joins into the handle are several diamond shaped marks from a locking tool of some sort as well as other marks.

The knife certainly looks aged but I’m not too sure what to make of it.

Does any of this check out for authenticity? I’m not familiar with this field of expertise.
