Unicorn

The company, based in Crockham Hill, Kent, was founded in 1937 by Frank Lowy. Lowy took the company as the reason for the fact that until then dart darts individually "from the bin", not sorted by size, shape and weight, were sold. Therefore, he made the first set of 3 dart darts named "Silver Comet". The company was dedicated to improving the material for darts and was able to present some of the developments that are now state-of-the-art in the sport of darts. Unicorn introduced in 1949 as an innovation arrows in different weight classes. Later Unicorn introduced today's one-piece built flights, from 1955 also in printed form. Further innovations such as exchangeable steel shafts followed. After the expiration of the patent protection for the sisal disk of Nodor manufactured Unicorn darts own disks, but also small accessories up to clothing.
