How to open a bottle of beer without a bottle opener

Step 3 Opening beer with sharp(ish) objects

This step by Vendigroth.
First off, a warning: Only do this when you're sober, for obvious reasons. Contradictory, I know, but you're using sharp objects in close proximity to alcohol, and I don't want you to get hurt.
Right, then; to business!
You need to put the tip of your knife (or the blade of your screwdriver, or the appropriate part of whichever tool you have) between the crimped edge of the cap and the top of the bottle, as seen in the first picture. Gently (gently being the key word, otherwise you'll end up wearing beer) lever up the edge of the cap.
Turn the bottle 1/5 of a circle and repeat.
Do this about 5 times, depending on how much metal you levered up each time, etc to get a cap that's flared out around the edges, or already very loose. When you've got a cap that's almost ready to let go, don't get cocky, otherwise you'll end up spilling the beer!
Instead, gently lever the cap off with your thumb, it shouldn't take much.
Again, i'd like to point out that you should only do this for your first and possibly second beers. Otherwise you might end up losing a thumb. Also, don't use knives that are too thin to survive the process. Razor blades are a definite no.
Have fun, and keep inventing ways to open beer!
