Hollow ground screwdrivers vs. tapered

[David Weaver]

How do you grind them? Just the first inch or so? And do you make the side parallel also?

I've been grinding them for things like making them thin to fit old cap irons, or shepherd in this case (my shepherd cap iron has a very thin slot), or grinding them thin and then cutting out the center to make a screw driver to split nut saws. Which I've had to do twice, not because the first one broke, but because i lost it.

I just use a bench grinder, and if needed, a hack saw. at $1, you don't have much to lose when experimenting.

That was pretty low down,William!! Grabbing a student's project. That would never have occurred to me as a shop teacher. It must have been a nice job,though!
