During summer I had a short tiem of practice with an electrical contractor. Since I was only on pratcice I had to use the other guy's tools. Tell you, there wasn't a single screw driver around that hadn't been beaten to death! Side cutters were the universal tool for everything, from stripping wires and cables to loosening or tightening nuts. I don't claim I treat my own tools too well, but I don't do stuff like that!
Using an old screwdriver for a chisel is common practice here. Plumbers also use their screwdrivers to nail copper pipe to brick walls until the mortar has set...
