The Axys modular axle system is the smart core in the new Henrys yoyos. The tried and tested Viper axle has been developed still further, and three more axles introduced, all of which are interchangeable with any Henrys yoyo for different playing styles. Colour-coded O-rings make it easy to identify the different axles.
