Do honing steels wear out?
I've been using my sharpening steel for several years. The tiny little ridges that run along its length seem to be somewhat worn, although they're still visible. I'm wondering if I'd get a better job from a new one, but they are rather expensive so I thought I'd ask first. Is there a way to tell when a steel needs replaced, other than just by the performance of the knives that are honed with it? I don't have a way to compare with a different sharpening steel, or a new one. Or are they the type of thing that you can buy one time and use forever?
