Stupid screwdriver ?

[Ton ton]

What is a keystoned screwdriver? I have seen them advertised in the SK catalog, but I was not able to make sense out of it. Thank you for putting up with my ignorant question.

It's the way the tip is cut. Keystone tips have the angled sides and cabinet tips have straight edges. The heavy duties are generally keystone.
