How to sharpen the blade of the lamb slicing machine

1. Put the blade on a rough surface test bench so that it will not run during the grinding process.

2. Add appropriate amount of dilute lubricating oil or liquid paraffin on the surface of the grindstone and wipe it evenly to increase the friction density.

3. Install the knife handle and knife holder on the slicing knife so that the knife edge is forward and lay flat on the grindstone surface.
