Aluminium-Flaschenöffner-Schlüsselanhänger

The slim 8 cm profile slips right into a jeans coin pocket, which is exactly where mine lives now. It's opened maybe twenty bottles this week without a single scratch on the finish, and the keyring hole is big enough to attach even with thick gloves on.

Weighs basically nothing at 9 grams, so it's been living on my keys for a month without me noticing it's there. The aluminum construction feels solid enough to actually crack a bottle cap cleanly, even after getting tossed around in my bag.

Finally found a bottle opener that doesn't take up half my pocket—the aluminum body is surprisingly sturdy for its 9g weight. The small size actually makes it easier to grip than the bulkier ones I've tried.
