  • front and “inner” used here refer to the forceps jaws of the screwdriver.
  • the “Front” clamping flank is thus arranged in the direction of the forceps jaw opening, while the “inner” end is in the direction of the base of the forceps jaw opening.
  • the tension side of the lower jaw is preferably curved in a convex manner to accommodate all of different sizes
  • the tension side of the lower jaw may be smooth or serrated.
