What is SharperBlade?

SharperBlade is a revolutionary rethinking of the classic string/line based grass trimmer. Instead of using string, SharperBlade trimmers use a single blade that is self sharpening, and longer lasting than traditional line. In addition, the SharperBlade is more impact resistant than traditional line and does not tangle or snag while in use. SharperBlade's serrated blade also produces a cleaner cut than traditional grass trimming line.
