The tips of wood-tip sticks are shaped into one of a number of standard forms using a lathe, depending on the model type. Nylon-tip sticks feature a hollow nylon tip contoured into one of a similar variety of shapes, which is mounted onto a post at the playing end of the stick and glued into place. Drummers tend to choose one over the other because of the way the tips react to cymbals – generally, wood tips provide a darker, woodier sound while nylon tips provide a sharper, brighter sound.
