I can open beer bottles using only my fingers. No putting in between your legs as a vice, just set a twist top on a counter/table top and unscrew the top using only a twisting motion with your index finger and thumb. However, some bottles are tighter than others. In my vast experience with this project, I concluded Alaskan Brewery beers are usually the hardest. I shredded many a fingertip mastering this athletic accomplishment, only to impress no one but myself.
