I very gently have muted the toes of all my razors, even the really collectible ones. It is not a matter of changing the shape of the toe, just taking that area from razor sharp to maybe "knife sharp". I do it because I am really happy with my earlobes just the way they are. My right earlobe learned the hard way, with a cut that was hard to close and is still visible one year later. I can return any of them to razor sharpness, still without changing the shape, with just a stroke or two on a finishing stone. I would never alter the shape of one of my razors, but that is not what happens when I mute them.
