Hand tools are used in nearly all occupations and industries. Modern tools have been enhanced with advance materials, external power and electronics. Some tools no longer have a mechanical connection between the hand and the work object, e.g., joysticks, computer mice and hand controls used for robotic surgery hand tools. Still it is widely recognized that tools must fit the user and task to achieve best possible performance. Failure to consider the user and task can result in acute or chronic injuries. Examination of tools from different applications and from different times offers many important lessons for tools designers and users. Panelist in this session will use historical and contemporary examples, models and standards recommendations for selection and design of tools.
