I’ve had this happen a couple of times and my attempts at polishing out the new scratches have been far less than successful. At a microscopic level, the scratches reach down into the grind scratch lines. This means that the only way to completely remove them requires that you do a regrind. Without fixtured equipment, any new scratch pattern you leave will be made obvious by the original lines.
A few of the fellows who visit here have polished their primary grinds to a mirror finish using just sandpaper. Just for show – not to repair a whoopsie.
If you were desperate to repair the damage, I’d contact Josh at Razor Edge Knives. This is what he does and he’s really good at it. Maybe he’ll chime in here. Or you can send him a PM – he’s “Josh” here on this forum. If nothing else but to see what the cost would be.
