Thanks to this thread I ordered some new screwdrivers for the hell of it. I already had the Wiha set from the original post but I think ill gift it to my BIL. I also have a set of Wiha precision screwdrivers in slotted, phillips, and torx for the smaller sizes and haven't found anything that uses the anything bigger than PH2.
