I have my Grandpa's knives, and both were veterans; one in the Navy and the other in the Army. The one that was in the Army carried a wooden scaled knife that looks exactly like those black handled "electricians" knives. I now have it and I used to carry it but it was old and the mainspring for the blade side broke. So now it resides in a box.
Its so worn I could never figure out what the lettering on the blade says.. I actually think its something like "Case & Sons" but like I said its really worn..
I also meant to say that I own one of those "US" Camillus knives. Its my current carry everyday knife..
never failed me yet!
