PET Bottle Opener and Closer Rev 2

If you homebrew and use PET plastic bottles I'm sure you noticed that after bottling and tightening 40+ bottles your hand gets pretty sore. This aid fits perfectly over a PET bottle cap and will enhance the torque needed to tighten these bottles, eliminating that problem, and doubles as a good aid to remove the caps when you are ready to drink them. Also great for various size pop bottles. Update: increased pitch on grippers as the old design wouldn't grip certain bottle cap types very well.
