Rings. I’m married and have a tungsten ring, so it’s basically always on my hand. Some bottles don’t give you much room to get under the cap, but I can get most anything open pretty quickly.

My favorite trick is using another bottle to open a bottle.

All that really matters is if its sturdy and small enough to catch over your knuckle and under the rim. Literally any object like that will work.

Lighter. I smoke, so I always have one handy.

Best/portable: Bottle opener keychain, most alcohol shops will give you one, there’s usually a beer doing a promo with them, just ask them because they probably have a box they keep forgetting to give out.

Creative: probably lawnmower.

I keep a corkscrew in my purse. It’s just nice to have

Learn from my mistake.

Car door latch. Fence bracket.
