Abstract Using the basic theory of human factors engineering, the author discusses whether various handles affect the human arm and shoulder muscles or not, while observing the work efficiency and accuracy by designing controlled experiment. According to Man-machine analysis of the hand tools, the paper studies on handle tool usage method, and creates a kinds of Z-shaped handle handsaw. The control experiments of new handle were conducted by sEMG measurement, and the author tries to understand and evaluate the effect on efficiency and accuracy. This study finds that fatigue degree is different between I-shaped and Z-shaped to arms and shoulders. Z-shaped handle handsaw is slightly better than I-shaped handsaw on the working efficiency, but Z-shaped has obvious advantages in accuracy which has an important enlightening effect on designing the tool handle.
