The precision grip differs from a pinch grip in that a pinch grip is static, while the precision grip is dynamic. When we manipulate objects normally the force acts at right angles. Utilizing a precision grip the force becomes tangent to the path of the apparatus' direction of motion and is distributed across the contact area rather than focused at a point.
