Hammerguns bench probably looks like mine. No two screwdrivers look the same.
Most from unkn or long forgotten sources but you can spot the good ones when you see them. They don't have to be pretty to be good.
I grind them on a belt grinder to what blade shape & width I need. Then file them from there for final fit if needed.
I've never liked the gadgety replacable bit type tools. Just seems to be a pain to work with and slows me down.
The breakage/replacement guarentee on some of them for the individual bits is nice I guess.
But I just could never see myself sitting around and waiting for someone to send me another screwdriver to use 'cause the one I have twisted or chipped the blade.
Make another one and go back to work.
