An instrument holder, which may be separate from or integral with the instrument for persons with or without physical disabilities. A central bore (1) enables insertion of instruments (2) of varying shapes. Gripping surfaces include a compound bevel downward and with a decided right or left hand slope. Elements from a top palm rest (6) to the lower planar surface (14) are volute, forming a right or left hand spiral. At the rear, the palm rest (6) curves aft and under terminating in the bevelled vertical detente. The hand specific side forms a concave surface (12) sufficient to accommodate fingers, joints, knuckles, or hand webbing between finger joints, flaring outward joining the lower planar surface (14). From the upper rear bevel detente, the back forms a slightly convex surface connecting with the bottom. The body and instrument path is reversible exposing the larger circumference area of the palm rest along with other control surfaces.
