Cue sticks, also known as pool cues or snooker cues, are essential tools for playing billiards. They are typically made of wood, with a tapered shaft and a tip made of leather or synthetic materials. Cue sticks come in various lengths, weights, and designs to suit different playing styles and preferences. They provide players with the ability to strike the cue ball accurately and apply spin or English for precise shots. A good cue stick is a must-have for any serious billiards player.
