Sure Shot Mc Gee

I considering to punch my own overshot cards to accommodate a proper roll crimp on 410 shot-shells. But I'm having somewhat of a problem finding a good metal punch around .410 dia. with a pre-sharpened cutter. I've ordered a couple of punches from weapons/parts supplier catalogs in the recent past and have had to return them. (both were lacking pre-sharpened cutting edges) I'm not very gifted in sharping rounded edges. A flat blade I can sharpen up enough to shave with. But rounded cutter hardened punches are a whole different ball game for me. Does anyone have a supplier in mind I can mail-order a proper tool from? The punches intended purpose would be for> thin plastic disks .410 diameter.
