Tru-Fire Switchblade Non-Barb Speed Tip 3pk Broadheads: * The Switchblade does not use any O-rings or rubber bands and yet it has rear deployable blades * Rear deployable blades means less kinetic energy is used to open the blades verses conventional "flip back" mechanical designs * The Switchblade will open on impact and stay open throughout the target * When the tip of the Switchblade makes contact with the target, the blades open up simultaneously * Because the blades are rear deployed, angled shots are no problem for the Switchblade * When the blades are in the open condition, they are locked in place * To close the blades, simply pull the tip and all 3 blades close down (without your fingers ever touching a blade) * No more having to worry about O-rings or rubber bands dry rotting and not holding your blades properly or even prematurely releasing 1 blade during flight which will cause massive erratic arrow flight * The Switchblade is truly mechanical * Blades are 440 stainless and .032" thick * Overall cutting diameter is 1-3/8" and the in-flight diameter is less than 5/8" * Another great feature of the Switchblade is in every pack all 3 heads will be hand weighed to make certain that they will be within 1 grain of each other for a matched set * The Switchblade has the same amount of cutting surface on all 3 blades as other 2 blade mechanicals that have a 2" cutting diameter * Because the Switchblade is a 3 blade, you have 1 additional blade to cut increasing your odds of contacting the vitals verses a 2 bladed head * The Switchblade will also have practice heads available that have the same external features of the live heads * Giving the practice head the same configuration as the live head you rest assured the 2 will fly identical
