The New STX Shift Sc-Ti attack shaft is an elite level offensive shaft. The "Shift" stands for the grip on the handle. The side that faces the back of the head has two sharp spines running the length of the shaft which create a concave slot on the sides of the shaft. The side of the shaft that faces the front side of the head is more rounded. It is designed to seat itself perfectly where the rounded part ends up on your fingers and your thumb fits right in the groove. Slightly sand blasted finish makes this one of the best fine grit grip shafts on the market designed for the guys that want to stay down on the tape weight and want something that feels like it fits in their hands perfectly.
