What is HHT?

Horse Hair Top?

Clay, I have to compliment you on doing some OUTSTANDING work demonstrating the capabilities of Nanocloth and Kangaroo.

I also want to make the point that using the WEPS platform to do this testing is a match made in heaven and a testament to what precise sharpening is all about!

Those micrographs are STUNNING and demonstrate beautifully what I've been saying about these compounds and strops and the importance as you get finer compounds of the effects of the substrate on masking the effects of the compound.

I hope you don't mind if I quote your work and use these pictures elsewhere to further promote your work and the products on the WEPS platform.

I could more obviously see that getting a 'pure effect' or compound only effect was critical at the higher grit levels like eighth and tenth micron snd finer, but your quarter micron pics strongly suggest that the nanocloth and 'roo may have additional benefits at even lower grits, possibly well below 1 micron. So I'm anxiously looking forward to the additional work on the coarser compounds I sent you with the additional nanocloth samples.

Using a surface that is smooth beyond the limits of light microscopy as a starting point for demonstrating other abrasive preps like the 10k Chocera is also a SUPERB way to demonstrate the scratch pattern of that stone without the confusion of residual coarser scratches. Again NICELY Done!!

Now when we go beyond eighth micron down to 0.025 microns we are talking about a particle the size of a small virus, so I suspect that the resultant scratch pattern will also be beyond the limits of ANY light microscope. Yet we may well see some differentiating characteristics in the way the light gets reflected from these surfaces using your current equipment. Something like the effect that you see using an ultrafine graticule as a prism (just wildly speculating here about what to look for) like you see doing spectroscopy. Perhaps a high resolution mirror effect visible at full magnification. Can't wait to see the results!

Very exciting work, Clay!

+1!!! My mouth is hanging agape with awe at what the 'Roo and Nano cloth did Clay! Startling microphotographs! I got to get me some of that Roo and Nano-cloth!
