Give your opponents a chill when you come to shoot with the Viper Cold Steel Steel Tip Darts designed for use with sisal dartboards. These darts are packed with features starting with the barrel, fashioned from 80% Tungsten and 20% Nickel. Tungsten is a very dense metal, able to create slimmer darts with the same weight as lighter metals; this allows for tighter shot groupings without sacrificing control, increasing your scores. Tungsten is a sign of quality and durability as well because of its density. A higher tungsten content will produce a slimmer dart profile than one with less. More tungsten in the dart increases the price as tungsten is a rare metal and its density takes more effort to machine. The increased price gives a higher quality barrel and can improve performance, increasing scores. Each barrel enjoys knurled bands and hand-painted rings, allowing your grip to remain consistent throw after throw. The Cold Steel Darts feature tough, lightweight Aluminum Color Master Shafts, for maximum durability. These shafts feature locking holes that allow a more secure fit to your barrel; you wonﾒt find yourself retightening these shafts after a shot or two. Finally, each dart is finished off with wild frigid graphics adorning each slim flight, for a chilling look. Each set includes six wide glide flights, three extra nylon shafts, and a dart mechanic repair tool. Barrels also feature a limited lifetime warranty!
