"In 2007 we found one small part of a pocket knife we were able to identify as an Easy-Open, bone handled, double bladed jackknife made by the Imperial Cutlery Company of Providence, RI between 1930 and 1945. This time we found the rest of the knife, except for the blades. It is now apparent that someone beat the knife apart with a blunt object, breaking it open for the express purpose of removing the blades. Why? To make spears for catching fish? We can only speculate, but at least we have a better understanding of what happened to the knife."
Heath Smith speculated that the pocket knife might be a Camillus model.
