The Copperhead is the 2022 Case limited-time vault release pattern. The Copperhead has been a favorite of enthusiasts for over 100 years. This pattern boasts an oversized “snake head” pocket end bolster that's designed to cover the blade tangs and reduce pocket snags. Glide one (or more!) into your pocket before the Copperhead slithers back into the Vault at the end of the year!
