Grip (tennis) In tennis, a grip is a way of holding the racquet in order to hit shots during a match. The three most commonly used conventional grips are: the Continental (or Chopper), the Eastern and the Western. Most players change grips during a match depending on what shot they are hitting.
This pencil grip uses the same hold as the basic tripod grip, with a triangle formed by the thumb, forefinger, and middle finger, but further up the pencil. Because it is similar to the basic grip, this is a comfortable way to hold a pencil for drawing, while allowing more freedom.
