Wear Plate Sharpening
The Wear Plate edges become rounded and chipped during use and must be
squared off to ensure efficient operation.
Tools Needed:
• Flat File
1. Secure the Wear Plate in a vise.
2. File the edge of the Wear Plate to take out any nicks and to square
rounded edges (Figure 58).
NOTE: If the Wear Plate is filed enough times that the proper gap between the
Knife and Wear Plate cannot be set with the Gap Gauge, you will need to
replace the Wear Plate.
