This is the best ASP grip enhancement available. It screws right on replacing your existing end cap. The Leverage Cap is textured solid steel and has no sharp edges. It enhances your grip and leverage by acting as a stop for your pinky and virtually eliminates the chance your baton will be lost during a swing. It is also a multi-functional tool that can extend your reach by allowing you to hook onto items in hard to reach places and it works great as a glass breaker when used as a hammer.
