Didn't know where to post this so I just started the ''Subsim mini instructables'' thread. Where we trade project ideas, project help and show off the finished product.
So I got this as a gift a few years ago and I finally decided to rebuild the handle.
Me and Oberon decided that it's most probably a Yugoslav M1924 bayonet. Not confirmed though.
My father (since a have an un-natural fear of rotary saws) cut these pieces of walnut wood for me. I chose walnut because it was lying around the garage and it was dark in color.
The trick is to cut a milimeter larger than it would be and just sand away until it fits. I also had a small step to consider here.
And soon you have a nice raw fit.

I used two small screws to tighten it to the metal one half at a time and just used a wood rasp to slowly shape it following the metal contour and a feel for how my hand would grab it.
And I got this.
This picture show them just held together with my hand, screws taken out.
I glued them together with a poliester fibreglass putty I ''acquired'' from my previous workplace. Lovely stuff, holds together better than any glue, does not run and does not crack. Riveting would make me screw it up badly, so I cheated with glue
I wont polish or lacquer it so it looks worn but I am tempted to put 4 small screws where the rivets would have been
