I really like an open beer bottle. I am sure there are some that love a closed beer, but I like to drink them. The Key Shark Bottle Opener assures that I can always open a bottle. I was given one of these little items as a gift, go figure. And while it is small enough to be forgotten on a keychain when the time comes you always remember it’s there. It is small, light (weighing only 1.14 grams) and unobtrusive. I now buy them as stocking stuffers.
