I don't have a suggestion at this moment, just here to confirm Knipex tools are awesome! I'm an electrician and use a lot of Knipex hand tools, and they are all super good quality. Most electricians only buy Klein hand tools, but they're quality has been slipping lately due to moving a lot of manufacturing to China, so a lot of us have been switching over to Knipex.
I guess I do have a quick suggestion, Wera screwdrivers, with the laser etched tips specifically. You can put in a screw in the ceiling, and it will hold itself in there upside down, and not fall to the ground, and they are not magnetic at all. Also I love the grips on them. I always bought cheap screwdrivers because anything gets the job done, but these make me so happy to use.
