If the knobs are hard to turn to release the the racquet you either had them too tight to begin with or too loose. Either condition will cause this problem. Over tightening on knob will make it hard to turn when you take it off that is easy to understand I think. But what about too loose? If the top or bottom supports are too loose it will cause the racket to shift while it is being strung and push up against the side supports too hard making them hard to turn when you finish.
Everyone has the right to be stupid... it's just that some people abuse the privilege...
