Quick Answer
To sharpen a fixed blade knife while in the field, use a sharpening stone or steel to create a sharp edge by drawing the blade across in a figure-eight motion, and apply consistent pressure to the stone.
Choosing the Right Sharpening Tool
When sharpening a fixed blade knife in the field, you need a reliable sharpening tool that can withstand the elements. I recommend using a ceramic or Arkansas sharpening stone, which can maintain its sharpness even in wet conditions. These stones are also relatively lightweight and compact, making them easy to carry in a pocket or backpack. For more aggressive sharpening, use a steel with a coarse grit, such as 120 or 150.
Sharpening Techniques
To sharpen a fixed blade knife, start by holding the blade at a 20-degree angle, with the bevel facing the direction you want the edge to sharpen. Place the sharpening stone on a flat surface or a rock, and draw the blade across the stone in a figure-eight motion, using consistent pressure to maintain the angle. Repeat this process several times, rotating the stone after each pass to maintain even sharpening. For a more aggressive edge, use a higher grit stone, such as 400 or 600, to hone the blade.
Maintaining Edge Health
After sharpening, use a leather strop or a sharpening steel to hone the edge and maintain its sharpness. This will help prevent the blade from becoming dull and will also remove any micro-scratches that can dull the edge. When sharpening in the field, it’s essential to maintain a sharp edge to ensure safe and effective use of the knife. Regular maintenance and sharpening will also help extend the life of the blade.
