Lead vices are used to hold lead in place while stretching, screws to a bench has a spring loaded mechanism.
It is best to strecth your lead came prior to using in your stained glass window as it removes any wobbles and kinks, whilst making it slightly more rigid. Take care not to over stretch as it can make the lead weaker, or snap! Keep a foot behind you in case you lose your grip or the lead breaks - this will save you ending up in a heap on the floor!
