The Ultimate Guide to Fillet Knife Sharpening Techniques

A sharpening fillet knife is essential for maintaining its effectiveness in slicing and filleting fish. Here’s a step-by-step guide-

Materials Needed:

  • Fillet knife
  • Whetstone or sharpening stone fine-grit stone
  • Honing oil or water – depending on the stone
  • Towel or cloth


Prepare the Stone: A whetstone soaks in water for about 10-15 minutes before use. If you’re using an oilstone, apply a few drops of honing oil to the stone’s surface.

Secure the Knife: Place a damp towel or cloth on a flat surface to create a stable base. Rest the whetstone on the towel. Precaution, hold the knife with the blade facing away from you.

Find the Right Angle: For fillet knives, a 15 to 20-degree angle is generally suitable. You can use the knife’s existing bevel as a guide.

Start with Coarse Grit: Whetstone has many grits. Start with the coarser side. Place the heel of the blade against the stone at the chosen angle. With light pressure, slide the blade across the stone in a sweeping motion, covering the entire length of the blade. Repeat this process on the other side.

Switch to Fine Grit: Established a burr on both sides of the blade with the coarse grit, switch to the finer side of the stone. Repeat the sharpening process, this time using lighter pressure.

Honing: After sharpening, it’s beneficial to hone the blade using a honing rod or a fine-grit section of the whetstone. This helps refine the edge and align the microscopic teeth.

Test the Edge: Feel the edge of the blade with your fingertip. If it feels sharp and smooth, you’ve sharpened the knife.

Clean the Knife: After sharpening, clean the knife to remove any metal particles or debris. A quick drying with a towel should be enough.

When using a stone to sharpen a knife you will find a small metal burr on the opposite side of the edge. Now, when the desired sharpness of the knife is obtained, give a few light passes on the other side. And remove this burr using a honing rod.

Make sure the sharpness is consistent along the entire length of the blade. The knife can checked for any spots that may have been neglected during sharpening. If you need less effort to cut, that’s a good sign.

Pay attention to the original angle of the knife edge when sharpening. Changing this angle can affect how the knife performs.
