" vise grips
swiss army knife
duct tape
coat hangers"

Duct tape is alway good to have in an emergency toolkit. I once was
stung by a yellowjacket on the forehead while camping with the family.
I did not feel confident my wife could drive while attending the kids and
pull a trailer, so I used the duct tape to hold my eyelid open, as it was
swollen shut...

Good tool recommendations, all!
