Usually the first thing that a trademan or handyman will learn is that they can't do much work if their tools are dull and dirty.
Before using or sharpening any tools, be sure to read and understand the manuels on how to use and take care of the tools. (If they come with one.)
It takes longer to repair a mistake than it does to sharpen tools. Usually with a tool that is already in good shape, it will only take a couple of minutes to resharpen it.
