A vibration dampening grip cover for the handle of an implement is preferably of multilayer laminate form having an inner vibration dampening layer and an outer gripping layer. A further inner force dissipating stiffening layer is included in the laminate. In a variation of the invention a grip cover is in the form of a sleeve which fits over the end of an implement handle. The sleeve terminates in a peripherally outward knob. The sleeve may be of a single layer made from vibration dampening material or may be a multilayer laminate.
