Cable shear has very sharp cutting edges, only around one third of the physical effort is needed when using the Knipex cable shears. This reduced effort substantially reduces strain for the fitter, particularly when using the cable shears for prolonged periods, e.g. For house wiring work. Due to a scissors action and precision ground cutting edges, the user gets a clean, technically perfect result after cutting cable, which is the ideal condition for work steps following the shortening of cables.
