The Harrows Strix Steel tip dart set is made of 90% Tungsten. Precision is paramount when machining intricate grip over the length of the barrel, which is testament to the advanced CNC facilities they have Harrows. Delicate ringed cuts, varying in width and depth, cover the barrel offering a strong grip, regardless of where a player holds the dart. The barrel is coated in heavy duty titanium nitride and re-cut to leave a striking black and silver finish. Strix darts are supplied with Midi Red Supergrip Carbon shafts, new Prime flights and are match weighed to +/- 0.05g.
