An ice hockey stick is a piece of equipment used in ice hockey to shoot, pass, and carry the puck across the ice. Ice hockey sticks are approximately 150–200 cm long, composed of a long, slender shaft with a flat extension at one end called the blade. National Hockey League (NHL) sticks are up to 63 inches (160 cm) long. The blade is the part of the stick used to contact the puck, and is typically 25 to 40 cm long. Stick dimensions can vary widely, as they are usually built to suit a particular player's size and preference. The blade is positioned at roughly a 135° angle from the axis of the shaft, giving the stick a partly 'L-shaped' appearance. The shaft of the stick is fairly rigid, but is slightly elastic to improve shot performance.
