Hockey Sticks
Hockey sticks, or in other words, rhythms, are one of the most important components of the game of hockey. In the past, they were made of solid wood, but now their stems are made of aluminum, wood, composite materials (such as kevlar or graphite). The stick blades used to be straight and now curved, made of wood or various composite materials, but not of aluminum. The curvature of the blade must not exceed 1.5 cm. These changes increased the speed of the hockey, its control.
