    Default Suggestions for rounding over sharp edges on engineers square and combination squares

    Suggestions rounding over sharp edges on engineers square and combination squares?

    I've just purchased reasonably in-expensive engineers square and combination squares.

    All have sharp edges.

    Any suggestions on how to make them not so sharp?
    Should I leave them?
    Can I dull them by microns?

    Thanks in advance.
    Thanks,

    Put a strip of emery on a flat surface and gently pull the edge in question along it. All you should be doing is taking the sharp off.

    A quick brush (light pass) past a wire wheel on the grinder?

    Usually enough to break the edge.

    Hi Barry,

    A quick swipe with a fine stone is usually enough.

    That was going to be my suggestion as well as that's what I have done.

    I found a Scotchbrite wheel is good for this sort of things,

    I know a well known boutique maker uses a 3m Scotchbrite debuting wheel on his bench grinder for just this purpose on his squares.

    Just remember that depending on the grade, that Scotchbrite can be might aggressive.
