The OMP fletching knob by AAE was engineered in the footprint of AAE’s ever-popular Bitz knob to have the same accuracy and smooth feel. Designed to complement the OMP Phoenix fletching jig by adding a precise and indexable way to fletch. Whether you need to replace a single vane with accuracy or add indexability when building arrows with glue on nocks the AAE OMP knob is the only fletching knob for the job. With etched timing marks installed on the face for repeatability, the AAE OMP knob stands out as the arrow builders’ choice.
