The Case Knives CopperLock is an American-made folder based on the classic Copperhead pattern. The main difference? It features a strong lockback mechanism (hence the name) that promises to keep your fingers safe from unintentional blade closure. It's a single-bladed knife with a classic nail nick opener and a razor edge poised to strike like a viper. No Case knife collection is complete without a CopperLock. Don't let it slither away—catch yours today!
