Gerber Bolt Action (7021)

This is another Blackie Collins design. It uses a sliding bolt to lock the blade open, a very strong lock. Apparently they also produced a longer, skinnier model called the Fisherman as well as an Orange handled serrated Fisherman called the Rescue. Meyerco also released a version later on the was partially serrated and had a thumbstud.

I like it, very simple and functional.
