I got there electric screwdriver- usb charged that has a ball grip. I think it works pretty good, at least for my usages, since I work in IT and electronics. They are great to open cases, installing components, disassembly, and assembly, etc.
I'm not sure if Fujikogu is related to the Fuji Tool Co. in Japan, but I do see a lot of screw gauges made by Fujikogu that are sold as vintage on ebay as well as other measurement gauges they make. They must be a pretty good tool maker if they make all sorts of accuracy measurement gauges.
