I got a set of DMT diamond plates a while back, and in the beginning they seemed to be fine... I got the 300, 600, and 1200, and now the 600 and 1200 seem to have grown a few "bumps" on them that nick whatever I'm sharpening... I got out an old plane blade, and used the top end to try to dislodge/break off the offending pieces of grit or whatever is on there... it worked on one of the spots, but the others seem to be unable to be dislodged...???
Anyone else have this type of problem, and if so, how do you go about fixing it...? I had to regrind one of my Hock blades to get rid of the scratches and right now I'm not using them any further until I figure out a way to fix the problem...
