The F-15 is the only broadhead with dual, side-by side cutting blades. The two razor-sharp blades give you 6 cutting edges and create a 250% greater wound opening than single blade broadheads. This means significantly greater blood loss, a better blood trail and ultimately, a faster kill. Fixed Blade.
I have killed three bucks in a row with my Carbon Express F15 broadheads. They leave a big hole and a great bloodtrail. I practice only with broadheads into styrofoam-these are the most accurate broadheads that I have ever shot. What a great product!!
