Quick Answer
To sharpen a fish fillet knife in the field, use a combination of a sharpening stone and a leather strop. Hold the knife at a 20-degree angle and draw it across the stone in small, smooth strokes. Rotate the stone and repeat the process until the blade is sharp.
Choosing the Right Stone
When selecting a sharpening stone in the field, look for a water stone or a diamond stone. These stones are effective at sharpening a variety of knives, including fish fillet knives. A 600-grit water stone or a 1200-grit diamond stone is a good starting point. Make sure to choose a stone that is compact and won’t take up too much space in your tackle box.
Sharpening Technique
To sharpen your fish fillet knife, hold the stone at a 20-degree angle and place the knife on the stone with the bevel facing up. Draw the knife across the stone in small, smooth strokes, moving from the heel to the tip of the blade. Repeat this process 5-7 times, rotating the stone after each stroke. Check the blade’s edge after each stroke to ensure it’s getting sharper.
Fine-Tuning with a Leather Strop
Once you’ve sharpened the blade on the stone, use a leather strop to fine-tune the edge. Hold the leather strop at a 20-degree angle and draw the knife across it in smooth strokes, moving from the heel to the tip of the blade. This will help remove any remaining imperfections and create a razor-sharp edge. Repeat this process 3-5 times, or until the blade is sharp and cutting smoothly through flesh.
