Kershaw’s PT-1 is a keychain tool with three separate functions: a pry bar, a flathead screwdriver, and (what you’ll use it for 99% of the time) a bottle opener. I’d also add a fourth though: packing tape breaker. It’s not a blade, so it won’t slice open a package, but it’d be useful for getting them started so you can claw them open with your fingers. Just $5, a steal.
