Common blade, flat-blade, slot-head, flat-idea, or flat-head / flathead screwdriver are all names for that unit used to generate a slot. additional torque can be supplied with no detrimental the screw head which has a hollow-ground screwdriver mainly because it is not as likely to cam out (go away the slot on account of the torque getting converted into an axial power, much like that seen with Phillips travel but relying only on driver blade).
