Tip grip is the most extreme grip type of the three, with minimal contact points between the hand and the mouse. This type of grip is only using the tip of the fingers to steer the entire mouse in extremely rapid movements with the least restrain of the hand and wrist. Mice chassis made to this grip type tend to be very light, very short and normally with the flattest back arch angle of the three.
Everything about tip grip is designed around speed, which it surely excels in. However, due to the minimal contact points and support of the hand, tip grip might not be ideal when the gliding movements are required to be slower, delicate and precise.
