Abstract This disclosure relates to a process for manufacture of grips for hand-powered equipment in which an assortment of grips are manufactured, each having a hardness within the range of that of the human hand. The hardness profile of the hand contact area of an individual operator who is to use the grip is measured, and a grip is selected, the hardness of which is correlated with the hardness of the hand contact area of the individual. This grip is installed on the hand-powered equipment for the use of that individual.
