Curious about what the ferrule on a billiard cue stick is
all about. The ferrule is the small section near the end of the pool stick
between the tip and the pool shaft. The major purpose of the ferrule is to
absorb the impact of a pool shot which will help protect the shaft from damage,
including breaks and splinters. The ferrule measures between ½” to 1 ¼ “ and
can be made from ivory, aegis, phenolic, plastic and metal. Ferrules can be easy to replace by slipping
on or screwing into the end of the shaft. They need to be replaced if they
become cracked or loose. A defective ferrule will alter the accuracy of a shot.
Check to ensure that the ferrule is smooth and slides through your fingers
easily, without any catches.
