If I had a dollar for every time I stabbed my hands or fingers with a flat head screwdriver I would be a rich man. I hate the flat head screws. I like the flat head screwdrivers though. One of the most useful tools in the garage just useless as a screwdriver.

My favorite is hex screws. I refuse to own a RC that doesn't have hex hardware. My XTM Rail came with Philips hardware and that has all been changed now. All my ohter RCs have hex hardware as standard fittment.
