I bought a GEM 1912 and EverReady 1914 off Ebay. They were identical except for the etched names. So, I bought another EverReady with a different handle to distinguish them. I noticed the head of this new EverReady was rounded, but I was surprised to see it opened "backwards." Instead of flipping up from the back, it latches in the back and pivots open at the front. Anyone have any details on the different designs?
