I'll answer soon guys - I promise

Josh - I think I found the answer to your problem... I'm doing the paste progression now, and it's confirming what I thought. Short answer, you'll need pressure when transferring from the 1K WEPS diamond to the 14micron paste.... Pictures to follow soon... I'm in the middle of sharpening now!

Is there a reason you think it might not have happened if the ceramics were lubricated, Clay? (I've wondered before what the main difference is between synthetic wet stones and the WEPS ceramics, why do wet stones need to be kept wet and the WEPS ceramics not.)

For what it's worth, I have never observed this amount of microchipping after using the 1200/1600 stones. (One stone progression I did can be seen here.) I have seen only a tiny amount, and Toms explanation of this (scratches from lower grit stones becoming apparent when polishing with higher grits) is quite convincing.

I thought this microchipping had also happened to the knife on the photographs in the grit chart and that it was pure coincidence that they showed up in the WEPS ceramics pictures and not in the Chosera/Shapton pictures.

Good points. My initial thought was that there might be metal particles on the stones that were causing the chipping so I want to try with soapy water to see if that makes a big enough difference to account for the chips in the image. I also want to explore any other differences between the stones and techniques for each one, moisture being an obvious one, hardness and friability being a couple others with the stones themselves. If the results aren't an effect of the stones themselves, then I guess it has to be technique, in this case, not enough time spent removing deeper scratches. I'm going to browse my images and see if there are other progressions I've done that include the ceramics.

In looking at these images further and going back through the whole progression, it looks as though I wasn't hitting the edge with the ceramics. I'm going to have to go back and do it again. I have a brand new Farid mule in CPM-REX 121 just asking for me to sharpen it and document the process.

Simply a bump for a great thread.
I wanted to find the Chosera progression again and I had to dig. This had almost fallen off of the recent topics list.

Yes, those Chosera and Shapton progressions are great!

If you just want to find back a threat, the search function on this forum works great . (It's the tab "Search" above, not the search box in the top right. The latter one is for the entire site.)

I am still interested whether Clay found any more results regarding the ceramic stones.
