Hand interfaces (11), (111), (188), (201a), (201b), (202a), (202b), (204), (211), (311), (411), (511), (611), (711), (811), and (911), which improve the performance of many items including: racquets for tennis and other sports; rotary hand tools such as screwdrivers; hockey sticks; and kayak oars. Relative rotation between one of the hand interfaces and a corresponding implement is selectively stopped, and torque is selectively transmitted between the hand interface and the implement, when a user squeezes the implement's handle. The hand interface can be rotated in either direction on the implement, and relative movement stopped at an infinite number of positions. The hand interface amplifies the opposing effects of either a firm grasp or a relaxed grasp. Tactile indicator systems (36) with (38), and (236a,b) with (238a,b), glove (204), as well as handle grips (611), (711), (811), and (911) which rotate on noncircular shafts, enable users to accurately determine rotational positions of the implement to the hand interface. For additional ease of use, adjustable end-stop systems (273a,b) with (275a,b), or (73f,b) with (86f,b) limit the range of rotation between the hand interface and the implement

1. A hand held implement including a handle, said handle comprising:a handle shaft having inner and outer ends and an outer surface, at least a portion of said outer surface comprising a first braking surface; a grip sleeve having inner and outer ends and inner and outer surfaces, said grip sleeve at least partially surrounding said handle shaft, said grip sleeve being temporarily deformable from a non-deformed state inwardly towards said handle shaft into a deformed state upon application of manual pressure to said outer surface thereof, retaining means for mounting said grip sleeve for rotation about said handle shaft when said grip sleeve is in its non-deformed state, at least that portion of said inner surface of said grip sleeve opposed to said first braking surface of said handle shaft having a second braking surface thereon; at least part of said portion of said grip sleeve containing said second braking surface entering into braking engagement with at least part of said first braking surface of said handle shaft to thereby prevent relative rotation between said grip sleeve and said handle shaft upon application of said manually applied squeezing pressure, said second braking surface disengaging from said first braking surface upon release of said manually applied squeezing pressure; said implement being attached to said handle shaft.
