Product details:

The cam operated helical groove design provides the user with the smoothest quietest most durable and roadworthy throw-off ever made. Close-tolerance CNC machined components are suspended in a special synthetic lubricant that give it an effortless and fluid movement. To increase resonance very thin rails keep the remainder of the body elevated away from the shell. It is manufactured from solid machined metal parts consisting of billet aluminum and stainless hardened steel.
