The purpose of adding counterweight to the billiard cue is to adjust the center of gravity of the bar and achieve a specified weight.

The billiard cue made of high-quality wood (such as ebony back handle, because the density of ebony is higher, it is easier to control the position of the center of gravity). Since the weight of the wood itself can meet the requirements, no counterweight will be added.

In order to save costs, poor quality rods are selected from poor wood. After the wood is taken too many times and the wood is too light, it is necessary to add a large iron bar of more than 10 cm in it. The purpose is not the center of gravity, but to ensure that the rod has a minimum weight. Therefore, the billiard cue is light at the front and heavy at the back, causing the hand frame to be too light and the back hand too heavy when playing. Therefore, high-end clubs usually have no counterweight.
