    Unique knife edge uses

    Hey guys, new to the forum.

    I was just curious, are there any other interesting uses you’ve come across for knife edged lenses aside from hyperopic rxs?

    I don't know about everybody else, but my top 3 uses for knife edge lenses are;

    Shave with one.

    Drill a hole in the center, attach a handle and use it for a pizza cutter.

    Fling them Kung Fu style at your enemies.

    Don’t forget, it is the one sharp object that TSA will never catch
    I bend light. That is what I do.
