Thread: Grit issues, does any one else see a problem here

As noted in the post, all edges shown are finished on an 8k Shapton Pro. The 80 grit wet/dry obviously is not optimal, that's the point I'm trying to make. I just don't have a new diamond plate to demonstrate, so had to make do with what I had available. A new diamond plate of any grit lower than 800 is WORSE than the 80 grit wet/dry. Once they break in a 325 is fine. Even a DMT XXC is fine. Look back and see what I said - if the 8k/16k guy is using a new, not well-worn diamond plate, that could explain the whole issue. (He did say he was sent a brand new DGLP to try, which is definitely going to produce a coarser finish vs. a more worn plate ). The sharp diamonds really do produce a bad finish, as well as allow pieces of stone to break away and act as slurry. The net result is a coarser finish and a very rough feeling edge.

The fewer laps you do with a coarser lapped stone the worse the finish will be. More laps lets the stone revert closer to its natural texture, as I stated earlier.
