Believe it or not, I actually like the Edge Pro polish tapes. I wish they would last longer, but I do like them. The glass blanks are supposed to be flatter than the aluminum blanks. Maybe so, but my question is: The stones are not as flat as the glass blanks. So, what is the point of using an ultra-flat blank? Is there any real-world difference between using the glass blanks instead of the regular aluminum blanks?
