    Thanks for the help.

    Yeah, the spurs are dull. The good news is you still have spur left, as far as I can see.

    Sharpen them on the leading edge to the peak of the spur ONLY on the inside of the spur.

    The cutter leading edges also look dull on some of them.
    Sharpen those only on the topside. Try to sharpen from the middle of the snail outwards,

    The traditional tool is a bit file, where one end has safe edges and the other has safe faces. I’ve found a coarse or medium eze-lap diamond card file works better. At least give it a try.

    And some of the snail tips look a bit dull also, which might make entry into hardwoods a chore. I sharpen those like you’d sharpen the tip of a birdcage (square) awl. Don’t remove any of the threads on the snail

    After you get them working, clean up the rust. ( overnight bath in vinegar will do it).

    And you will know they are dull again when they get hotter in use than new or sharp bits.
