Leatherman is an iconic American company at this point, but they don't rest on their laurels. A sweet piece of innovation that benefits our men and women in harm's way is their MUT, a multitool with features specific to maintaining and repairing firearms.
The MUT is a little beast of a tool, weighing in at an even thirteen ounces with the enclosed MOLLE sheath. Along with the usual assortment of blades, pliers, and drivers are some more exotic and interesting tools: wire cutters, electrical crimpers, a hammer (yes!) and a replaceable cutting hook.
When it comes time to work on your bang stick, there's a bolt override tool, cleaning rod/brush adapter, punch and carbon scraper. Feel the need to solve your problems with high explosive? No worries, there is an EOD version as well with extra features for working with blasting caps.
The MUT is useful not only for soldiers and law enforcement, but for anyone needing to operate a firearm in the backcountry. If you've ever had to depend on your rifle, shotgun or handgun for food and safety while far afield, you'll appreciate the extra margin of independence provided by the MUT.
