The Armbar Slim Drive takes a minimalist approach while giving you the tools to help you with what you do the most: cutting, driving, and opening a beer. A 2-1/2" long driver with a two-sided 1/4" bit has the reach to tighten that fastener without busting your knuckles. Not to mention the easy one-hand access to the 2-1/2" frame lock blade that can rip through anything you put in front of it. Don't get caught unprepared, support your daily carry with this robust tool in your pocket or on your key chain to get out of any jam.
