We’ve covered a ton of bottle openers here on the Upscout, but I can say this is officially one of the smallest we’ve seen that actually works. The JO (Just Open…see what they did there?) is a tiny titanium .5 in by .8 in tool that can pop open your beverage if choice. no extra features, tools, functions or gizmos. The JO is just that, just an opener. There are still some available at the early bird pricing of $9 if you pledge quickly.
