Fold the edge over, rubbing in on something will most likely just sharpen itFold it over by 1/2 inch or so, press or hammer it down tight, then fold it againNot only wil it not be sharp, but it will be stronger along that edgeOne way to fold it over is to clamp the edge between 2 square edged boards and use your hands to bend it to 90 degreesAfter that, use the board to flatten it outWear glovesGood luck.
