we are going to need a way to shape,grind this blade right? o.k. im going to cheat a little here. i just so happen to have ,onhand, a flat piece of old sandstone sidewalk. however, i know in my heart, that if i spent enough time by the maumee, id find a flat broke off natural piece of sand stone. i have in the past. but for right this minute, i have this piece.and water from my rain barrels instead of from the river itself.Tony
