I've bent both of my window crank handles very carefully and not too
much with no problem.  I've done it more than one set as well since I
keep yanking the knobs off cause I'm too aggressive at tolls (EZ-Pass
has helped). As long as you don't mind black crank handles, you can get
them for $5 each at a flaps when you bend it too far (snap).
