When stowed properly, folding knives don't expose a blade, making them convenient for camping since they are versatile and take up less space. A folding knife can come in different sizes and shapes for various purposes, like the Opinel No6 with a 2.7-inch blade or the MIKI Sharp folding Japanese style camp kitchen knife with a 5.5-inch blade. Whether you are planning on using the camping knife for food preparation or cutting paracord, make sure you get the right one.
