An Evaluation of Handle Shapes and Sizes

In many industries there are numerous hand tools in use which vary considerably in handle size and shape with no apparent reasons. This research sought to investigate capabilities of males and females on two thrust maximum force tests, using various shapes and sizes of handles. To accentuate the characteristics of each size and shape, the force tests were conducted with the coefficient of friction between the hand and the handle surface reduced by the use of a disposable plastic glove and the application of a slippery film.
