Abstract: The function and advantages of a split hook and a mechanical hand are combined into a single unit obviating the complex and difficult process of interchanging hook and hand units while at the same time providing the dexterity of a hook for grasping and manipulating small objects and the prehensile function of an operable locking thumb including extending holding times without the need for cable manipulation. Covering the split hook members with finger-shaped material and adding rigid fingers enhances the cosmetic appeal of the unit.
