BRISTLE DARTBOARDS
Tournament quality bristle dart boards are made of natural sisal rope fiber. (Sisal fiber is made from the leaves of the Agave plant, the same plant species from which tequila is made.) These rope fibers are compressed under tons of pressure and banded with steel, then bonded to a non-warping backboard.
The surface is later sanded smooth and then screen-printed with the appropriate colors. Finally, the wires attached and the number ring attached with clips, to allow easy rotation of worn areas.
The English company NODOR first developed bristle dartboards in the 1930's, and introduced commercially in 1936. Before that time, dartboards were generally made of elm wood, although the NODOR company also made a plasticene dartboard.
Note: It is a common misconception that dartboards are made of animal hair, such as pig bristles, camel hair, or horse hair. This is a myth... No such animal fiber boards have ever been made!
Also, the spelling "Bristol Dartboard" is incorrect. The name "Bristle Dartboard" refers to the sisal rope material that the board is made of, not the city "Bristol".
Top notch boards are the Bulls Advantage (In American Bandit Boards, the same) Winmau Blade 3 & 4, Unicorn Eclipse to name a few.
