Lefty stylists who are told that reversing the screw set on their shears converts them from a right-handed to a left-handed shear are delusory. A right-handed shear with a reversed screw set is just that: a right-handed shear with a reversed screw set. The shears will still bend and fold hair like a regular right-handed shear - the screw set is now facing your palm rather than away from it.
