I am new and I hope I can date this knife. It appears to have 2 blades, 1 clip and 1 pen with a leather punch. On the main blade is BOKER U.S.A. on the back of same blade is 85 tree 93. Clip and pen on the same end and the leather punch is on the opposite. The leather punch has the edge to put your nail under and on the opposite is, what looks like lines going from edge to edge, about 1/16th of an inch apart. There are 12 of these such lines. The shield has a tree, but under the tree are the words Tree Brand. The body is a serpentine with jigged bone? Thanks Sam B.
