It's not very sharp
I am not much of a fan of it. When I ordered I was hoping that it would be as sharp as the one I got from simply carbon fiber. It was not this one is pretty dull with no sharpener.
Sorry for any confusion, carbon fiber as a material is not great as a cutting knife, it just doesn't get that sharp. That's why we have this note on this page: "Carbon fiber blade will not replace your steel blade, consider it a novelty item." With that said, carbon fiber can be carefully sharpened with sandpaper.
