Very interesting guide by CalOSHA on selecting non-powered tools and considering ergonomics. This guide includes handles, grip, motion, and a range of other factors.
Think hard about this guide – we focus on powered tools, vibration, torque, and other factors, but for using non-powered tools requires all manual power. Think about assembling something from IKEA with standard screw drivers – then, multiply that by 8 hours a day, 5 days a week. Yes, that bad.
