Sirius AM - 3D Printed Open Source Project

Sirius AM is the first balisong trainer in our open-source project lineup.

Our open-source projects are released to the public so anyone can make one for personal, non-commercial use. Sirius AM was created to make balisong flipping more affordable, accessible, and available to more people, in more places, anytime.

We will also make Sirius AM available directly through our website, offering one of the most affordable and accessible entry points into the balisong community for those who prefer a ready-made option.
