STOP -
it is only sharpened on one side!!!
if you sharpen it on both sides you defeat the nitrate coating !!!
if you look at the edge you should see only one side is sharpened and the coating
on the other side goes to the edge and in fact is the edge!!!
if it is other wise you need to send it to buck to re-edge it!!!
if it is not touched on the other side use a lanskly to maintain a
even edge angle !!!
