3D Printed. PDGA Approved. Tanto features a wide rim and blade-like edge, making it the most stable flight of all Forge discs. The concave bottom edge on the Tanto is the counterpart to the convex edge on the Fuller. As with all Forge first runs, we have not yet settled on the official flight numbers for this disc. Sometime after your purchase, you will receive an email with an opportunity to share the numbers you think best describe the flight.
