...So here's how I modified the key to my '92 Honda Civic to moonlight as a bottle opener.
TOOLS & MATERIALS:
- Key (car keys probably work better than house keys - so opening a bottle will be a reminder not to drink if you're driving!)
- Bottle with cap still on
- Dremel tool with cutting wheel and high-speed cutter drill bit
- Safety glasses (protection from the metal dust)
Step 1: Figure out the geometry of your key as it relates to a bottle
I'm sure there are dozens of different key geometries that would work just as well.
Step 2: Cut away material with a Dremel tool (get under the cap's lip)
I focused first on getting the key under the lip of the bottle cap. I cut a pointed tooth (sharp corners rounded off) that allowed enough of the key head to wrap around to the top of the bottle cap and provide leverage (the next step).
