I have two bottle openers on my key chain currently. Yes it is unnecessary but they found their way on there and now they are part of the key chain family. On of the problems that I have with them is that they take up a lot of space and often feel like they are going to break when opening a well sealed bottle. I was browsing the net the other day and came across a really neat bottle opener that blends into a key chain perfectly.
How cool is that thing? It looks like a key but has an area specifically designed to be a bottle opener. It looks like it is build out of fairly thick metal as well. The only concern that I have is about leverage. There doesn’t look like there is a ton of room to gain enough mechanical advantage to make opening a bottle easy. It costs under $8 on Amazon so it might be worth a try.
