DANGER

Never use any H.K. Porter cutters on

energized circuits, wire, or cable.

How to Sharpen Cutter Jaws

• Remove nicks in jaws by filing straight across cutting edges

• On jaws with equal bevels, file equally from each bevel, keep file

flat against bevel

• On jaws with one large bevel, file on that bevel, small bevel must

also be restored

• Jaws should not be razor sharp

• Approximately 1/64" (.4mm) should remain flat to form strong,

durable edge

• Adjust tool according to the instructions below

• To sharpen shear-cut blades (blades that pass each other like

scissors) remove nicks by filing straight across cutting edges

• Finish by running a flat file over inner jaw surface to remove burrs

• Choose file size according to size of jaw and/or radius

of curve

• Half round files are the most versatile

• An adjustment screw is located on the cutter

handle above the toggle joints

• If jaw edges are too far apart with handles

closed, tighten adjusting screw, this brings

cutting edges together

• Cutting edges should be 1/64" (.4mm) apart

for longest jaw life

• Oil all joints

• If jaw edges are too close together with the

handles apart, loosen adjusting screw until it

disappears from the narrow slot in the handle

• Make a cut with the tool in this position (cut will

force the slot inward)

• Try to close the handles. If they do not close

completely and jaw edges are 1/64" (.4mm)

apart, tighten adjusting screw to meet the

handle on far side of slot

• Oil all joints

• If jaws are too far apart with handles closed

after making cut with adjusting screw backed

off, tighten adjusting screw as explained above

• To sharpen shear-cut blades (blades that pass

each other, like scissors), remove nicks by

filing straight across the cutting edges

• Finish by running a flat file over inner blade

surface to remove burrs.
