My experience with the strops is that the tackier the better. I get the best results when my strops are really grabbing the metal.

I received my micro ceramics last week. After using them on a few knives, I was pleased with the results until I lapped them last night and used them on a knife this morning. MUCH better results to say the least.
I started at the 100/200 and progressed up through the 800/100, rotating the ceramics after about 8 to 10 strokes. I used a bit of dish soap on a sponge to wipe off the stones and ceramics to clean out the debris on the each. I couldn't be more pleased with the mirror edges after lapping the ceramics.
Unrelated to this, I'm having problems with cleaning and loading diamond paste on my strops.
I cleaned them really well, smoothed them and loaded them. When I use them, I am getting residue left on the edges and them seem a little sticky or tacky. Any thoughts on this??

I had a different result as far as mirror edges. I sharpened a Kershaw Blur from 100 diamond thru 1600 ceramics. Then I switched to 5,000/10,000 Choseras before going on to the 1.4/0.6 micro ceramics. The mirror edge after the 10,000 Choseras was great, to the naked eye. But after the micro ceramics, the mirror edge had changed - inconsistent polish thorughout the edge that just didn't look right. Has anyone else noticed this?

However, at 400x magnification, the edges seemed about the same.

I couldn't get the lightening right with regular photos showing the mirror edge difference but I did take some 400x photos of both 10,000 Chosera and 0.6 micro ceramic edges.

After 10,000 Choseras:



And here are two more photos of the same blade after the 0.6 micro ceramics (different lightening):



This is just one knife so I'll try some more after lapping the micro ceramics.

Not quite the same experience. But tonight I sharpened another knife, finishing with the micro fine ceramics and again I noticed some scratches similar to the ones in the first photograph of the edge in my blog post. Don't know exactly why.

Clay, can you tell us why you think lapping the stones would be a good idea?

For two reasons - 1) I had noticed that one of the brown stones had a rougher surface than the other 2) I'd read somewhere that the only difference between the Spyderco Fine and Extra Fine stones was how they were finished i.e. they were the same stone but one that was lapped to a finer surface which led me to think it would be worth a try since the same company (Coorstek) that is making our stones makes the stones for Spyderco. I'll try to dig up the post I read for reference later. I contacted my rep at Coorstek to ask about it but he didn't know anything and is supposed to get back to me.

The quote about the F and UF Spyderco stones comes from Cliff Stamp on his blog:
Spyderco has always been clear that the only difference between the F and UF is the lapping finish, they are the same abrasive one is just finished finer than the other.A bit of perspective on the razor community, while they are correct, they are extremely precise and the main guage they use is the sensitivity of the skin in response to shaving as the guage of sharpness.

When I first used the micro fine ceramics (esp. the "brown" stone) , I did notice a different scratch pattern on the edge, however, after lapping them, the scratch patterns appear to be much more refined and consistant although I am not looking at them under 200x. Just my 2 cents but I'm curious to see other results.
