As noted, earlier, there are multiple different ways to sharpen a blade, and, as long as you are able to achieve the sharpness desired, who is to say your way is wrong. I started with a wet-stone and belt and 'graduated' to a steel and a razor strop. A rock, in the woods, for some, may be what is needed; although \I have not be successful with one, to date.
Bottom line - a dull knife will not cut properly, while a shape one will cut everything; including fingers. Where does one get a Chain-male glove?
