In my old Brit gunsmithing book it tells/shows how to make screwdrivers from old car springs. Then they are used in a brace so the 'smith's weight can be properly applied to the screw hahaha. Obviously technique is central to not buggering the screws. And undeniable force with that brace

Fabbris use torx screws. Perazzi prolly would too if they had any screws of any consequence.
