Tim, that screwdriver looks exactly what I used to make by hacksawing the middle of the blade except that it looks a little neater. I never dreamed there was a tech article describing how to make them. I figured they would have some kind of Kent-Moore tool recommended. At one one time, I had a 1/4 drive socket similar to the T-handled thing. I was looking for it the other day and I found one with a knurled handle the other day that I forgot I had. All of the gadgets like that work.
