That's interesting. Thinking back over thirty-plus years of buying various bits for hand-held and electric screwdrivers (my dad was using battery powered Makitas before I graduated high school in 1984), I can't remember the last set that I bought which didn't include Pozidrive.

And so far as I know, I've never actually encountered anything that used Pozidrive, so I've always thought it was a huge waste that they were always included.

TIL.
