The entire purpose of the design, engineering, machining and production of this amazing broadhead is to ensure pin point accuracy.  Not only will the flight of this concealed blade broadhead allow you to place your pin on the spot you want to hit, it allows you to get your arrow to that exact spot.  With a simple change of a set screw, you can put this broadhead into practice mode and the blades will not deploy ensuring not only a broadhead you can practice with, but a broadhead that you can perfectly practice with.  You will not ding up your blades, you will not ruin your target.

Note: The blades do expand upon contact and with a 'load' on the blade, both parts of the broadhead are locked together for extreme strength thru out the wound channel.  When that 'load' is released, the blades are allowed to 'de-barb' and escape from an errant shot.
