I've been doing some regular maintenance (painting) on my house and today while in Home Depot to get more paint I saw this at the counter while waiting for my paint to be shaken (not stirred :-). I have always used a screwdriver to open the can and it's about time I had a proper paint can opener. However I never really considered needing a bottle opener while painting but they may be correct because a nice cold bottle of beer sure tastes good when I'm done for the day!
