MNTBK3B: BK-3b Bottleneck
Mantis Knives

The introduction of the "Bottleneck Family" was a milestone for the Mantis brand. This series of knives was our first collaboration with Hawk Designs of Idaho City, ID.

Gavin and Grant Hawk have long been friends of the Mantis organization, so it was only natural that we eventually collaborated to bring knife enthusiasts one of the most unique gadgets that the knife-marketplace has ever seen.

The Bottleneck design boasts a bottle opener, butterfly knife which attaches effortlessly to any keyring with it's integral handle/latch configuration.

I love this knife and carry it in parades as part of an American Legion color guard.the only thing that caught me off guard was how small the knife was for the price.but all and all I love the knife.its good looking and functional.

A bit large for a keychain
A nice little novelty knife. I question the use on a keychain; although the lock is fairly strong it WILL slip off. Built fairly well, everything seems tight. The blade is very sharp. and the finish is good.

Pros: None
Cons: Handle Feel
Nice novelty
I bought this as a gift and I find it a nice gadget. No real use. The handle just is too short to use this knife for anything else than opening letters. All in all, it´s great fun.
