I use a screwdriver when I have to (so I am a level 0 expert) but at some point you have to release your grip on the screwdriver and therefore need a way to keep it engaged in the screw (except if you reposition it at every 1/4 of turn). This can be annoying (it is always for me) and a mechanism where you can arm the next 1/4 turn without disengaging the screw is great PS. when I say 1/4 of a turn, this is to to indicate the torsion of the wrist. Could be more, could be less
