Eastern players, generally speaking, often prefer the Penhold. It’s a “reversed” grip, with the handle of oriented downwards as though holding a pen.
There are three major variants on the Penhold grip: the traditional Chinese Penhold, the Japanese/Korean Penhold, and the Reverse Penhold Backhand. In general,the Penhold is as much a style of play as it is a grip:
This grip allows the wrist to move quite freely, which will give good forehand strokes and all types of serves. It also allows the player to block and push easily on the backhand side.
Another advantage is that the player does not have a crossover point where he must decide which side of the bat to use, since the same side is always used to play all strokes.
