I have noticed on my knife and other knife that when I run my thumb across it to see how sharp it is, it seems sharper when going in one direction and duller from the other direction. I am trying to figure out what this means and what exactly I am doing when I am sharpening it to cause this. Is it even a bad thing? It is particularly noticeable closer to the handle of the knife, where one side seems sharper. I tried checking it visually to see if the edge was uneven on one side, but as far as I can tell with my eyes it looks fine. Any help is appreciated!
