Abstract: A grip for a tool handle or other surface intended for gripping by a user, may be provided by a durable, expanded elastomeric material. Formation of the grip, and installation thereof on a handle may be effected to provide pre-loading of a normal force against the handle, requiring substantially less normal force by a user on order effect frictional engagement of a handle by the grip. The grip may also be formed to provide micro-pressure along ridges impressed into the hand of the user alternating with cavities in a surface of the grip for receiving intrusions of the hand. Thus, mechanical engagement, rather than strictly frictional engagement may be effected. Grips made in accordance with the invention have been demonstrated to provide sufficient engagement with a hand and a tool handle to permit a user to apply the maximum physical force available from the user.
