The Pico Bottle Opener ($11) is so small it will virtually disappear on your keychain. The creators wanted to make and opener that utilized otherwise wasted material from their other products. What they came up with was a small, yet effective, Titanium bottle opener that is smaller than a quarter. All you do is hook the opener onto your bottle cap and use a little leverage, to pop the cap. Easy peasy. Right now you can pre-order the Pico from the companies crowdfunding campaign on Kickstarter.
