So my brother left his 1670CF154 (limited edition Kershaw Blur with CF and a CPM-154 blade) in the engine room of a boat he was working on and one of the other employees found it. My brother thought it was lost for months until the other day he sees this guy with it sharpening it on an electric grinder. In short, he gets the knife back but it has bad scratches in it. Kershaw wouldn't be able to replace the CPM-154 since it was limited edition so is there anything short of sanding or a regrind we could do to get them out? I considered re-tumbling it but the thumb studs might be messed up and i believe they're pressed into the blade.
