After 12 months of design, Target eliminated traditional radial
grooves with their pioneering new Cortex grip. The milled cuts at
the heart of Cortex are cut axially along the line of throw to
enhance grip and guide when you need it, and promote release when
you don't. The Carrera Azzurri Cortex dart comes complete with
Target Pro Grip Blue Vision Shafts and Target Vision Flights.
