• 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
