It's hard to image improving on that handle design. It's even good with the hard, slick plastic handles of my old cheap Craftsman screwdrivers. I hate handles where I have to figure out and copy how the designer expected me to grip it. I have no idea how my hand grips my Craftsman screwdrivers, and I don't care. The handle has a bunch of ridges, our hands have a bunch of bumps and ridges, just grab at any angle or grip you want, and the bumps and ridges find a way to catch on each other. The one aspect that could be improved is that the older ones I have are from the 1970s and probably wouldn't work well for people with larger hands.
