How to Sharpen a swiss army knife
Learning how to maintain and sharpen your Swiss army knife is an important skill for campers and backpackers. You will need to have a sharpening stone that can be dry or wet. To use a wet stone simply add a little bit of water or homing oil. Keep the blade at an angle of 5 to 7 degrees from the surface of the stone and move the blade back and forth or in a circular motion.
