[7] Devil sticks vary widely in size and construction materials, but the batons are generally based on one of two basic designs: tapered and straight.
Devil sticks are usually constructed of wood, plastic, aluminum, or composite materials such as fiberglass or carbon fiber.
They are most often covered with an elastomer that both increases the friction coefficient (grip) between the baton and handles as well as providing some protection against repeated drops.
Flower sticks have flower-shaped ends which slow down the movement of the baton and make learning some moves and tricks easier.
Illuminated devilsticks can create interesting visual effects in darkness with the use of battery-powered electric 'seed' bulbs; LEDs; or with phosphorescent or chemiluminescent materials.
