    Carla, if you have "real" disc cutters, the ones that have punches
    that fit into a die block, it will be do-able and worthwhile, maybe.
    There's cheapies that are just punches that aren't worth buying. The
    problem is that you really need to keep the end of the punch square
    and straight to the shaft, which means a lathe would be the tool of
    choice. Plus they are tool steel, which means using sandpaper and
    elbows will be a lot of work - sandpaper runs the risk of actually
    dulling the punches by rounding the edges instead of sharpening
    them. But yes, if you leave the shaft alone and just take the end
    down to a fresh edge that's of a reasonable precision somehow, no
    reason not to. Even an electric drill mounted in a vise and some
    sort of toolrest and a stone could do a fair job of it, if done
    well.
