Picked it up at he Dugger gun show today and don't know much about it. The main blade has Case XX with six dots then USA underneath. The numbers on the other side of the blade are 640045 R. It has the main blade, a bottle opener, can opener, and some type of punch type blade. One end has a metal loop pinned to it. The box doesn't have the model number on it. There is a tag , but it might be the store that sold it's number. It says style 7715. Any info would be appreciated.
