Anyone got a step by step how to do them or diagrams at what the racket should look like when doing one?
Do you play at any clubs or take any training with a coach? If you can find someone resourceful from there to teach you how to slice it'd be much better and accurate and not to mention less confusing than someone here describing you in words or you may not even understand the diagram and do it wrong. Not that I don't want to help you but you should learn right from the start and not have to go back and correct a bad habit.
