This meant dropping down to 320 grit and hand sanding furthur to undo the damage done by the dremel. On a wedge this mistake is recoverable. On a hollow ground I would think the junk drawer would see a new victim.

Bill makes it look easy with his big grinder on his video, zip, zip, done. BUT you would have to ruin a lot of blades to have his touch.

I will likely continue to try to master dremel with a gentler touch and reduced rpm but you have been warned. If the blade has any value either sentimental or money hand sanding is likely the safest way to do the least damage.

Sixgun's (glen) experiments with the shell casing polishers seem to be as safe or possibly safer (appears to work with fine etch) depending on your choice of media in some ways but it's hard to beat 40 hours of careful selective hand sanding.
