Three Useful Tools To Sharpen A Fillet Knife

In order to hone a fillet knife, you must equip yourself with the necessary tools. Sharpening is made easier by these tools and will ensure your blade stays sharp for longer periods of time!

Sharpening Stone

Professional-grade knife sharpening is done with a whetstone. The stone provides better control and allows more precise pressure to be applied to the blade of your knife. However, it requires practice and advanced skills before you can use one confidently.

We recommend practicing on cheaper knives first so that if anything goes wrong, no harm’s been done!

Here’s how to sharpen a fillet knife using a sharpening stone:

  1. The first step is placing the stone on a flat surface and solid so it doesn’t wobble around while you’re doing this.
  2. Pull it at a 20° angle across a whetstone with one hand. Use four fingers from another hand to push down on the side of the blade to increase pressure.
  3. Then, flip over to use that same motion coming from each side of where you started, always moving forward towards you as opposed to back and forth.
  4. Flip your fillet knife to the other side. Make a motion starting from the edge of your sharpener closest to you and moving towards yourself. Be careful not to injure yourself!
  5. After that, flip it back over and repeat on the other side. Do this three or four times before flipping it back over again to do another round of sharpening on both sides. Once you’re finally done with that, you’ll have a shiny new knife!
