Sharpen the bevelled edges:

If using a file, hold it at a slight angle against the blade’s bevelled edge and move it in smooth strokes away from you. Repeat this process until a clean, sharp edge is formed. Using a grinding wheel, use light pressure to grind down any nicks or dull spots on the bevelled edges.

Sharpen the flat side: 

Flip the blade over and repeat the same process on the flat side to remove any burrs and achieve an even cutting surface.

Repeat if necessary

Once you are satisfied with the sharpness of your blade, use a cloth to spread a light coating of protective oil to control rust and decline.
