Gunther's post about the nut twister (hey, keep it clean [Linked Image] ) reminded me of my Ideal cabinet - tip screwdriver with a twister built into the handle. Great for those of us with Pre-Carpal tunnel! (Keeps the wrist happy... happy is good!)

I also love my Ideal BurMaster conduit fitting screwdriver/ EMT reamer. 1/2", 3/4" & 1", just like the Klien version, but much shorter, and carries a spare blade inside the handle.
