The changes from the Type 1 consists of the cut on the grip, weight, and the maximum diameter. On the barrel, elevation has been added to the ring cut to increase its gripping ability.
At the end of the barrel, stair-like cut has also been added to allow one to feel the end of the barrel easily and to prevent holding the barrel too far towards the back.
Super micro shark-cut is placed at the front of the barrel to assist the grip by the middle finger. The maximum diameter was increased by 0.2mm and weight by 0.5g from the previous model.
With these changes, and the barrel’s center of balance being at the back, the barrel has evolved to respond well to one’s throw and help propel the dart towards the target.
