The first Winmau Blade dartboard was released in 1997 and revolutionized the game of darts by removing all staples and offering the thinnest wiring available, making it the most technologically advanced dartboard of its time. Four generations later, the Blade 4 dartboard continues to pioneer new technologies and bring dart throwers the thinnest wiring available. The Blade 4 has been used in professional tournaments around the world including the Lakeside World Championships and Winmau World Masters. The Blade 4 is also approved by the British Darts Organisation (BDO). Advanced molecular structure of the high tensile steel facilitates total accuracy right across the whole playing surface.
