A deformable grip (10) for handheld implements such as writing pen (20) and other handheld equipment such as shaving instruments, medical instruments, sporting equipment, and similar articles, which is capable of being deformed in conformance with the user's s hands and fingers. The present grip (10) includes an elastomeric sleeve (40) filled with a magnetorheological (MR) fluid (60) and a magnetic field generator that acts upon such fluid to adjust grip deformability. In a preferred form of the invention, the implement body (32) or other equipment handle is configured to include a recessed cavity (35) wherein the (MR) fluid-filled sleeve (40) resides. A permanent magnet assembly (34) is disposed within the tubular sleeve (40) such that in an on-state of the present grip (10), the magnetic flux field extends radially to pass through the (MR) fluid (60) to instantaneously solidify it in a relatively nondeformable set condition in conformance with the user's anatomical contours. In an off-state of the grip (10), the magnetic flux field is diverted from the (MR) fluid (60), which reverts back to a soft, deformable condition. The deformability of the grip (10) is controlled by a sliding mechanical mechanism within the pen (20). In an alternative embodiment the deformabilty of the grip (10) is controlled by an electromagnet (65) electrically interconnected to a miniature battery (66), a switch (67), and a varistor (68) which permits adjustment of the voltage applied to the electromagnet (65).
