multitool

Leatherman.

 

don't get the keychain, mini or ones with plastic colored handles.

 

if it's not heavy, grey and can hurt you, you probably have the wrong one.

 

this one has sawing knife for rope, a finer knife for cutting filament, screwdriver, wire cutters, pliers. and optional bit-kit.
