Fine Motor Skills
As a child develops, they can hold and manipulate tools (eg. spoons, pencils or scissors) in a controlled manner. For precise control, this requires the use of the thumb, index and third fingers to hold the tool and some stability of the fourth and fifth fingers.
The shape that is formed by the tip of the index finger and thumb touching is referred to as a "web space". The web space ideally forms a circle when holding a writing tool for precision and stability.
