Grim Reaper Broadheads pioneered the innovative Razortip Technology that secure razor sharp mini-tip blades to the Trocar tip. The Fatal Steel Trocarazor II tip features a cut on contact bone splitting scalpel. With no rubber bands and no O-rings, these mechanical blades stay closed until impact even when fired from the fastest moving bows. Grim Reaper has rewritten the book on mechanical razor broad heads! The blades float independently on a spring shock absorber. This means no deflection, and no kick-out, even on steep angles or sharp quartering shots
