Abstract
An adjustable handle and method of adjusting the cross-sectional shape of a handle is disclosed. The handle comprises a central core having a plurality of axially extending grooves each having at least two radially extending ramps as well as a sleeve having a plurality of flexible expandable members with a plurality of fins in sliding relationship with the axially extending grooves and ramps. When a user turns a knob of the handle, the sleeve is directed to slide axially within the groove such that the fins of the flexible expandable members contact the ramps thereby altering the cross sectional shape of the handle over an axial distance.
