Can anybody explain the right technique to use a sharpening steel to touch up the edge for 3-4" folder? I bought a steel for about $3.00 and I also wanted to know if the price range of steels is large and if quality of the sharpening steel is that big of an issue. It is made of chrome vanadium. I also ordered a Spyderco Sharpmaker 204 so how many times would you say I should use the steel to bring back the edge before I know that I need to use the sharpener? I do mostly light duty cutting such as food prep or small packages but nothing that would be heavy use on my blades. Thanks for the help.
