The Civilianaire knife from Mantis is a small and handy tool that can easily fit in your pocket, whether it's the fifth pocket or any other pocket of your choice. The Monarch MCK-3 version of this knife has a stunning abalone handle, measuring only 1-3/8" across and about 1/4" thick. Inside the handle, you'll find a sleek hawkbill style blade made of polished 420 stainless steel. It's worth noting that this blade does not have a locking mechanism.
