The BK-3B Bottleneck from Mantis is a collaboration with Hawk Designs of Idaho City, ID. Gavin and Grant Hawk designed the Bottleneck design, which boasts a bottle opener and a 50-state legal butterfly style knife which attaches effortlessly to any keyring with its integral handle/latch configuration. The BK-3B knife features a bead blast finished Tanto style blade!

The action on this knife isn't ideal for serious flipping, but it makes a fun keychain knife that safely conceals and locks the blade when not in use.
