The EVO-X CenterPuch Broadhead was designed to provide long-range accuracy, durability, strength and performance. These 100 grain arrow heads feature a collarless design for accuracy akin to field-points. The blades on the EVO-X CenterPunch are as sharp as a surgeon's scalpel, and stay closed during flight. Upon impact, the blades deploy creating a massive wound channel for a humane kill that leaves large blood trails.
