I've actually seen the magnification pictures also of before and after stropping a cartridge on a piece of denim. It went from a rusty pitted to a shiny smoother look, which I would have to contend if a piece of metal is smoother and shiny it might be sharper. Considering the most extreme tip is is probably the only part that does the cutting in actuality, the difference could be noticed or not. It might just be cleaner as far as contaminants go.
