I've got a knife that's just like pic related (pic isn't mine, but I couldn't be bothered getting mine out).
I think it was issued to my grandfather in WW2 and then sat in a cupboard for decades. I cleaned it up and now it's a great little knife. It doesn't hold an edge too well, but it has a marlin spike and a can opener.
