ABSTRACT
This chapter describes specific hand tool design features that help minimize physical stress and maximize
task performance in jobs involving the continuous or repetitive use of hand tools. An important objective
of ergonomics in the design, selection, installation, and use of hand tools is the reduction of muscle
fatigue onset and the prevention of musculoskeletal disorders of the upper limb. It is not just the tool
design, but how a tool is used for a specific task and workstation that imparts physical stress upon
the tool operator. Consequently, there is no “ergonomic hand tool” per se. What makes sense in one situ-
ation can produce unnecessary stress in another.
