Constructed of die cast alloy
Clamp is precision ground to assure identical blade matching, right and left helical clamps are ground with a radius to achieve a true helical fletch
Hollow recess allows for thumb and fingertip control preventing slippage in the hand
Graduated scale at the rear base of the clamp allows for consistent spacing of feathers and vanes accurately from the nock
Knife edge on base of the clamp eliminates build up of surplus glue
Note: The steel plate is cased into the straight clamp, unlike the right and left helical where it is glued on
