The Cobalt 90% tungsten dart series provides an elegant experience for any player. The process to make Cobalt darts requires 6 stages: first, the front goes through a high-tech process with a Japanese CNC machine. Then, it’s treated with titanium nitride coating and the process is repeated with the back. This blue, tough coating provides a stunning appearance and sturdy, dual-function grip. The final cut produces forward and backward grip protrusions. Finally, the darts are match weighed to +/- 0.05 grams and paired with Supergrip Fusion shafts and Retina flights.
