The Case Copperlock is a traditional pocket knife with a mid-lock. The Copperlock has one wharncliffe-shaped blade. You easily open it with two hands. Because of the groove on the left side of the blade you have a lot of grip on the blade. The slightly bend handle might remind you of a Trapper. The name comes from the Copperhead model. You immediately recognize that influence from the lightly protruding bolster. It ensures that the sharp edge of the back of the blade gets stuck behind the edge of your pocket. The fact that the name Copperhead evolved into Copperlock is, of course, because of the addition of the lock.
