I’ve had a Brewzkey on my keychain for a number of years now. It’s really handy and doesn’t add much to your keychain (I prefer to keep mine simple without any unneeded bulk added).  Since you always carry your keys, you always have a bottle opener and all good craft beer lovers should keep a bottle opener on them at all times.  You never know when you may need to pop the top on a tasty bottle and you don’t want to be caught unprepared.  It’s built of quality metal and hasn’t had chunks strip away over time like I’ve had happen with the cheap 99¢ aluminum openers at the liquor store checkout.  Checkout the Brewzkey here on Amazon.

As you can see on my old Brewzkey, it’s been redesigned and I like the rounded look a lot more.  I just might have to pickup a new one.
