Quick Answer
Short Answer: The best method to sharpen a survival knife is using the 'whetstone method' with progressively finer grit stones, starting from 1000 to 6000 grit, for optimal edge retention and sharpness.
Choosing the Right Stones
When selecting stones for sharpening a survival knife, choose ones with a coarse grit (1000) to remove metal and create a bevel, and a fine grit (6000) to hone the edge. Diamond stones are another option for their durability and effectiveness. Always start with a clean, flat surface and use a lubricant to prevent metal from sticking to the stone.
Sharpening Techniques
To sharpen the survival knife, place the blade at a 20-degree angle on the coarse grit stone and draw it across the stone with light pressure, maintaining consistent strokes. Apply more pressure as needed to remove metal, but be cautious not to apply too much pressure and round the edge. Once the desired bevel is achieved, switch to the fine grit stone and repeat the process, this time with lighter pressure to hone the edge. Repeat this process several times on each stone to achieve optimal sharpness.
Honing and Maintenance
After sharpening the survival knife, hone the edge on a leather strop or fine grit stone to remove any micro-scratches and maintain the edge. Regularly sharpening the knife and maintaining the edge will ensure it remains effective for various tasks in a survival situation. Consider keeping a small sharpening kit with you, including a whetstone and strop, for quick edge maintenance.
