I Hate shifters.
Their main purpose in life is rounding the hex heads on bolts.

I guess my favourte would be the good old 4 way tyre iron. Makes the most satisfying holes in things, and you can pretens it's a man sied shuriken.
I never go anywhere without a Tanto Blade folding knife though. My current one is a 1* (1 ass to risk) military grade.
