It’s the most monumental development in broadhead technology since the original Gravedigger. The Gravedigger Extreme hybrid mechanical broadhead delivers even more devastating results than its predecessor. Hardened stainless steel blades create a deadly 2¼-inch cutting diameter. Further propelled by a 1¼-inch fixed blade with a chisel tip, the Gravedigger Extreme penetrates the hide then deploys inside for maximum blood loss. 1¼” cutting diameter main blade with chisel tip 2¼” cutting diameter mechanical blades 420 stainless steel blades 7075 aircraft aluminum ferrule Patented Blade Retention System keeps blades closed until entry No rubber bands or O-rings Guaranteed to cut no matter what No-failure broadhead True field-point accuracy Designed for use with compound bows and crossbows
