Using the same patent-pending multi-directional interlocking hexagonal ball interface, a corresponding wrist joint component was developed to provide adjustable mechanical positioning and secure locking of attached grips or tools across multiple axes. The assembly allows angular adjustment between 0 and 45 degrees around a full 360-degree central axis, after which the attached device may be rotated 360 degrees around the newly selected axis for additional positioning flexibility. A notched geometry permits extended articulation of up to approximately 70 degrees in one direction to enable closer positioning relative to the body. The wrist joint also includes a free-swing configuration that allows unrestricted rotation within the spherical socket when unlocked. This wrist component is compatible with both the Hexa-Flex Modular System and traditional lamination-style body-powered forearms, and it may be removed from either configuration for servicing or maintenance. The 35 mm hexagonal ball lamination-style wrist joint is currently designed to interface with 50 mm and 54 mm sockets.  Future renditions are being developed for smaller sizes.
