Ok folks, I need educating. I wanted a MINI SOCOM w/black blade but got an unbelievable price on the bead blash so I took it. Now the blade looks all scratched up from cutting up some cardboard. I'm having a hard time believing these minor cutting chores will cause permanent abrasions on the blade. Can they be buffed out? Will tough cloth work? I am more concerned with performance than looks but I may sell this knife and would like the blade clean. Any suiggestions?
