Step 1: Simply put your knife on the first stage of the sharpener to remove the blunt edge. The electric sharpener features diamond grinding stones that handle this initial process. Due to the thinness of fillet knives, avoid exerting pressure, go slow especially at this stage.

Step 2: Next, increase the sharpening angle (20 degrees is fine). Although it works automatically.

Step 3: While at it, pull back and forth 4 to 5 times. This stage ensures a finished factory-level sharp edge for any cutting or fishing adventure.

Similarly, you can use water while you are sharpening your knife. Remember to place it on a steady surface, with this initial preparation, you are good to go.

To get started, follow this simple guide:

Step 1: Start slowly and strike your knife edge using 12 to 15 degrees angle then boost up your speed. Not too fast though to avoid hurting your hand via the knife-edge or tip.
