Upgrade the most trusted fletching jig in archery with the AAE Bitz Knob Standard 3-4. Designed as a precision vane spacing receiver for the Bitzenburger jig, this upgrade eliminates the frustration of uneven vane alignment by delivering perfectly consistent spacing every time. All three-vane indexing options (120°, 90°, and 75°x105°) match the original, ensuring full compatibility with your preferred configuration.

Built with a wedge system that locks the nock into the same location with every arrow, the Bitz Knob provides positive engagement for both hunting and target nocks without extra adapters or inserts. Whether you’re building new arrows or repairing a single vane, the adjustable set screw allows quick alignment for one-at-a-time repairs without rotating your nock. From micro shafts to big game setups, the AAE Bitz Knob guarantees repeatable accuracy, consistent spacing, and smoother arrow building for serious archers.
