The World's Smallest Bottle Opener
The PiCO. The smallest bottle opener in the world, that then became the most popular bottle opener funded by Kickstarter. Solid titanium, made in the USA, and tiny....like, really tiny.
Using a sturdy split-ring for leverage, and placing your thumb on the opposite side of the cap to lift, the PiCO makes quick work of bottlecaps, requiring only a single tug to remove a cap.
