I always carry a Gerber MultiTool, not issued to bad... We get a knife issued, but after you cut yourself for the first time its blunt... Always fun to see the new recruits getting there equipment.. We tell them "watch out the knife is sharp" and stand ready with bandaids, and they are like, you dont need that... Untill they pull there finger on it to see if it is sharp....
I do like the multitools, i think these should be issued standard, especially when your a mechanic like me, even tho you have a big case of tools the multitool always comes in handy.. I know i use it regurarly..
