Yup, I do the same thing. About every third time I pick it up, I have to unwind the cord.
They make "swivel plug" extension cords where the male end swivels 360°. What we need are power tools with swivels on the tool end.
I got dibs on the royalties when someone comes up with a design...
EDIT: Hmmmmmmmmmmmmmmm
I want second dibs if that rotating plug will help, I'm bout ready to try anything even a cordless grinder.
