Old Pocket Knife "Our Boy" This interesting collector’s pocket knife could be English. On both sides of the gray metal are a relief of a sailor…..perhaps World War 1. Under that are the words OUR BOY. The length of the knife is 2 5/8 inches (7cm). There is a single blade 2 inches (5.3 cm) in length. This would be a handsome addition to any collection.
