In the reverse penhold backhand grip, the back of the penhold bat is used to hit the backhand. Typically the fingers are held in a similar fashion to the traditional Chinese penhold grip.
It is most common to put inverted rubber on the backhand, and use the backhand to produce a topspin ball which has a significant amount of left to right sidespin (for a right hander), due to the natural movement of the arm and racket.
