The Case Copperlock takes its inspiration from the Copperhead pattern, designed for everyday use and named for its resemblance to the shape of a snake's head, particularly in the knife's bolster. While the original Copperhead featured a slip joint mechanism, the Copperlock upgrades to a robust lockback system, ensuring the blade stays open and prevents accidental closures, keeping your fingers safe. As a staple of American craftsmanship, a Case knife collection wouldn't be complete without the inclusion of a Copperlock.
