I don't know if this is as amazing for you all as it was for me but I had to share. On a recent trip to home depot to buy paint the guy working the department gave me one of these paint can openers, they had a whole bucket full. It looks like this:
Anyway, it was great for opening the paint can. Then I realized it can also open those paint can lids on cocoa without me resorting to bending a spoon. The icing on the cake is that the rounded end is also the best bottle opener I've ever used. It doesn't even bend the caps so I can save the extra special ones.
In short: free kitchen gadget that is actually useful.
