Razorback Helix 125gr Broadhead 3pk - features single bevel, aerodynamic design, means it works in tandem with the fletching. This is a unique principle in broadhead design - steering from the front, which results in greater overall stability in flight. The secret to creating the helix effect comes from the sharpening process. While the Helix Arrowhead may appear to be a simple two-blade design, the offset sharpening process yields a unique hunting broadhead that is forced to rotate in flight. 3 per pack.
