I have one of those, conveniently small, but the taper leaves
something to be desired if you are working on nice screw slots
that you don't want to damage.

The pocket wrench has a slotted screw taper that widens on both
sides, so is gentler on screws. Its other features-bottle opener,
ruler, hex drive, wrench and pry bar are well thought out too.
It is heaver and you only get one for the price.
