Hi-Speed Ergonomics - The ergonomics relevant for Direct fastening tools
Direct Fastening tools are popular for quick fastenings in concrete and steel by propelling the nail with gun powder, gas or electricity. Because of this the users hand needs to absorb a shock caused by the recoil when a setting is performed. The link between the recoil and its effect on the user is essentially unexplored. This makes it hard to design an optimum handle for a direct fastening tool
