TruFire's Switchblade Broadhead, the first Tru mechanical broadhead with no O-rings or rubber bands. Upon contact with the target the tip is pushed in, deploying and locking the blades into place before the broadhead even begins to penetrate the target.  Deployment requires less than 3 pounds of force, and disspates none of the bone crushing kinetic energy of your high performance compound bow. The design of the SwitchBlade gives you full-bore cutting diameter from entry to exit.  TruFire's Switchblade gives you the most gruesome blood trails ever followed, but don't expect to be following the trail very long because with the hole the Switchblade cuts, death comes swiftly and certainly. The TruFire SwitchBlade's rear deploying blades won't deflect on even the most extreme angled shots. To Re-Set the Switchblade to the closed position simply pull the tip back out. 100 Grain 3 pack. TruFire Switchblade Broadhead.
