All you need is this neat keychain. No, it doesn't just open bottles when you've forgotten to bring a bottle opener. This one also comes with a phone cord for convenient, on-the-go charging!

The stripped-down Shard DT offers fewer functions than its predecessor. Then again, numbers aren't everything.

The OHBO – the One Hand Bottle Opener – is just a simple 3D printed ring that fits over a water bottle. There’s a small arm attached with a few bolts that lock this ring onto the bottle.
