WHAT YOU SHOULD KNOW ABOUT CHIPPER KNIFE MAINTENANCE
Properly maintained chipper knifes will give you longer service. When knives are badly abused you can
usually only expect minimal sharpenings before the knife is worn out. With proper maintenance and frequent
knife changes, you can get more knife sharpenings per edge. When sharpening knives, proper grinding
techniques must be used.
