Mantis BK-2B Bottleneck Knife
The Mantis BK-2B Bottleneck Knife is a collaboration between Mantis Knives and Hawk Designs. It boasts a bottle opener and a 50-state legal butterfly knife and it will attach effortlessly to your keyring with its integral handle/latch configuration. The bottle opener can be accessed and used while the knife is still attached to the keyring, so there’s no worry about forgetting your keys or your knife because they’re attached for life (or at least until you have to go through airport security). $39.99
