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. 21g •Diameter 6.9mm •Length 49mm 22g •Diameter 6.9mm •Length 49mm 23g •Diameter 7.1mm •Length 49mm 24g •Diameter 7.2mm •Length 49mm 25g •Diameter 7.4mm •Length 49mm 26g •Diameter 7.4mm •Length 49mm
