So I have this W&B wedge that I've been working on, and I've put a 3" sanding wheel on my drill to have a go at the blade to take the pitting out. Pitting is kind of deep. What harm can be done by grinding down to the bottom of these pits? As in, how deep can I go before affecting the integrity of the razor? I see the very edge crumbling away, as to be expected, and I'm a little nervous about rushing forward without asking this question.

Thanks in advance
