To achieve Cobalt’s elegance, the finest 90% tungsten goes through a 6-stage process. The front of the dart is turned using our new Japanese CNC machinery. It is then treated with a tough, blue titanium nitride coating & re-machined to leave a stunning, dual-function grip. The back then undergoes the same process with the final cut producing forward & reverse grip protrusions. The finished darts are match weighed to +/- 0.05 grams & teamed with Supergrip Fusion shafts & Retina flights.
