Review on 💪 Experience Unmatched Performance with United Abrasives SAIT 57510 Aluminum by Ananta Crowley

I use them to sharpen knives, axes and anything with a blade. Just sweep the burr from side to side half a dozen to a dozen times and it's ready for steel or a polish that will razor sharp just about anything. This way I can razor sharp a dull serrated knife in 3-5 minutes. I took off a star because a box of ten is probably more than I've ever used, so the other 8-9 were a waste of money.
