It took a lot of time to develop our self nocks, we tried many technics, like the ones used during the victorian era, but we thought it wasn’t satisfying enough.

An inner massaranduba insert reinforce the shaft, and lateral reinforcements are made out in many different kinds of precious woods. The natural abalone indexers are available in yellow, black or green.
