A lot of the old Stanley planes have slotted (yuck) screws (e.g. the fence and depth stop screws as well as the "nicker" screw on the #45 shown in the photo). I currently tend to get a screwdriver bit holder handle and then rummage around for a bit that's the right size. I've got some bigger Wiha heavy-duty screwdrivers that would do the job too, but I wanted something fairly short and dedicated to dealing with old-fashioned woodworking tools. These two are sized to suit the screws on the #45 but they seem to fit quite a few others as well).
Starting with a couple of bits of silver steel, I ground these to shape on the bench grinder, filed a flat on the shank (to help some epoxy bind them into their handles) and then hardened to cherry red and tempered to purpley-blue (as per the recommendations for screwdrivers in the little book I use for reference). I then gave them a good clean up with wet and dry paper.
Today I turned a couple of handles for them:
