Well, I wish we could see a close-up of your drawing. It looks like museum-class stuff to me.
I wound up with the knife sharper -- but not where it should be. It will sometimes slice-cut newspaper when the side of the paper is held vertical and a shallow slice angle is made. It wouldn't do that before. It won't come close to cutting hair. It is, of course, more than sharp enough for field dressing a deer.
