Quick Answer
Sandpaper can be used for minor touch-ups and fine-tuning your survival knife's edge, but it's not a substitute for whetstones due to potential scratching and damage.
Choosing the Right Sandpaper
When selecting sandpaper for your survival knife, prioritize a finer grit (1200-1500) for polishing and a coarser grit (80-100) for more aggressive edge repair. For wilderness use, an 8-inch by 3-inch sanding block is a valuable addition to your kit, ensuring consistent strokes and preventing the sandpaper from getting in the way.
Using Sandpaper Effectively
For minor edge maintenance, wrap a small piece of sandpaper around your knife’s spine or use a sanding block to hold the paper firmly in place. Keep your strokes smooth and light, applying gentle pressure to avoid scratching or gouging the blade. Work in small sections, focusing on high-wear areas like the heel and spine. For more extensive repairs, use a whetstone or sharpening steel for better results.
Safety Considerations
When working with sandpaper, protect your hands with a leather glove or a cloth to prevent cuts and scratches. Wear safety glasses to shield your eyes from flying debris. Keep a small, clean workspace with good lighting to facilitate precise control and avoid accidents.
