After discussion of removing the duct tape requirement to create a screwdriver in this thread I worked up a quick and simple mod to make a screwdriver using a rag, string, sinew, thread, or plant fiber for the handle (or duct tape if you really want to, but that would be stupid it takes 20 more than the standard screwdriver recipe). Much like a makeshift knife. I named it a Survivor Screwdriver and made it slightly heavier and higher in volume so it is just a little bit inferior to the standard version of the screw driver.
You can find the mod here.
