Three tapered razor-honed blades are fixed on the one-piece, 440 stainless steel cartridge that rotates around the ferrule. The cartridge is easy to replace, and it stays firmly in place. Patented dimples on the cartridge reduce air resistance. Per 3.
I use these broadheads and have no problems. Their one piece design is easy to use and seems safer. They fly nicely and pass through easily, almost to cleanly.
Broadheads fly true. I tolk a forty yard shot and got 3/4 penetration in the shoulder of a 12-pointer which ran only 60 yards . Solid broadhead, no damage to head and went threw soulder joint. I will use the broadhead again with a new inset!!
