Those funny screwdriverish looking tools can still be bought.
The old time auto parts store loaned me one of theirs said I will like it so much I will want to buy one. I said this looks familiar to me.
When I got home I went into the museum, my dad's tool box where I keep his oldest tools. There in his tool box was three of them.
Next time I went back to the parts store I said thank you for loaning me the tool for just in case. Though would you like to buy some of them from me for my dad has three. We both had a laugh.
Though that link from DADS50 is great for it appears no special tool is needed.
