Chipper Knife Sharpening
• You should never attempt to sharpen the Chipper
Knife freehand.
• It is extremely important to consistently maintain the
40-degree angle for proper performance (Figure 44).
• Excessive heat generated during the sharpening
process will damage Knives and weaken the metal. Be
sure not to overheat the Knife during sharpening
because it will shorten the life of the Knife.
• Take the Chipper Knife to a machine shop for proper
sharpening.
• 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.
