My Dad happened to pick one of these nifty things up last year, and he hasn’t stopped using it. The Beer Hammer is the perfect beer gadget for the DIYer. It looks like your basic hammer, but instead of a nail remover there is a cap remover. The hammer is a bit smaller than a normal hammer as well, but it does have some weight to it (as I found out when I dropped it on my foot).
You can now do work around the house and open a few cold ones as well. I have got to tell you that the caps fly off when you use this thing, I guess it has to do with all of that leverage and stuff. Just Google “Beer Hammer” and you will find tons of suppliers for the product. Most of them seem to be right around $10 or so. This is a gadget that is actually useful as well as fun to use.
