3 Step Sharpening Process

Sharpening Made Simple

Step 1:

Place the knife sharpener flat on a secure work surface. With light pressure pull the knife straight down 4 – 8 times keeping it in full contact with the carbide rods.

Step 2:

Lift the sharpener up on edge and deburr the edge on the right hand side of the sharpener.

Pull the blade across the edge alternating between each side of the blade.

Step 3:

Align the knife blade to the right of the honing slot, slide the blade all the way to the bottom of the slot. Pull the knife through with smooth constant pressure 8 – 12 times.

note: If the knife was badly damaged you may need to repeat steps 1 – 3 over again.
