    Has anyone else tried taking a raker file to cut the shiny part of rocked teeth back then sharpened as usual.
    I tried this method on my last mistake and seemed to work well. A lot less time than filing back with a round file.
    Other experience welcome.

    That is was my preferred method before I had a grinder. I used a flat file & eyeballed the witness mark and took the tooth back until it was cleaned up. I would use a magic marker on the edge so I had a little visual help making sure I didn’t leave a small flat on the cutting edge when sharpening. I still use the flat file if the teeth are really goobered up.

    I always grind chains that have been rocked.

    I have not but recently learned of nicked teeth on the drive links when a chain is thrown.

    When you hit a rock ,dirt ,nails , etc.. with your saw ,and really mangle the cutters . You can also approximate a rocked chain running it dull for a log time .

    If you happen to hit a rock by accident or because you hit dirt by accident or a rock embedded in the wood the corner of the cutter can be bent. So usually the cutter has to be ground back or filed back far enough to eliminate that bent portion to make it cut correctly again.

    If I have a really badly rocked chain, it’s quicker for me to use a round file to remove damage, then go back to square. A good sharp round file will remove material rather quickly with a decent amount of pressure.
