The Winmau Blade 4 utilizes a revolutionary new wiring system that dramatically reduces bounce outs and provides the opportunity for maximum scoring potential. It’s predecessor, the Blade 3, set the standard as the World’s finest staple-free dartboard and the Blade 4 has taken this to a completely new level. The DSW (Dynamic Sector Wire) is now over 50% thinner for best-in-class performance and optimum scoring possibilities. This unique wiring system is constructed from a hi-tech, ultra strong material that is designed to deflect the darts into the target area. The advanced molecular structure of the high tensile steel facilitates total accuracy right across the whole playing surface, whilst lasting even longer. The Blade IV also keeps the same self-healing sisal technology as the Blade III.
