Knife Sharpening

 You should never attempt to sharpen the Chipper Knife freehand; take the Knife to a machine shop for proper sharpening.

 It is extremely important to consistently maintain the 45-degree angle for proper performance.

 Excessive heat generated during the sharpening process will damage Knives and weaken the metal.

 How many times a Knife can be sharpened is determined by how much material needs to be taken off to sharpen or to

compensate for dents or gouges.

 A new Chipper Knife has a 5/16" measurement between the short side bevel edge and the Knife mounting holes (Figure 24).

 The knife should never be sharpened to the extent that more than 3/32" is taken off this measurement.

 Once this measurement is below 7/32" (Figure 25), or if you are unable to remove dents or gouges with these guidelines,

replace the Knife.
