Says "Plugable USB2-MICRO-200X" on the base.

I know my id is "mhosea", but you can call me Mike. It's an old Unix thing.

What I find most interesting is how smoothness changes when the scale changes too. Thanks for the pictures.

A lot has been written about these very fine abrasives in the wood working and knife making communities. I've found the Grand Unified Grit Chart very useful for comparing abrasives, always using micron size as  a "real" number <https://docs.google.com/spreadsheets/d/1VaTf3MXuwuvH-QLwOci4f9B9Zhkbuu1wjoSCZIUsR-o/edit#gid=0> 


I find the 3M Microfinishing film 0.5 micron sheet <http://www.leevalley...004&cat=1,43072> to feel noticeably finer than the 12,000 Micromesh but I don't know on what scale the Micromesh is measured so I have no objective means of comparison. The Micromesh has a cushioned backing whereas the  Microfinishing film has no such backing and is typically used on a glass plate or polished steel substrate. One could try using the film on top of a sheet of sponge rubber (many types and densities) to approximate the built-in cushioning of the Micromesh.

I'd strongly recommend spending a bit more and getting the diamond abrasive version of these same sheets. The abrasive is attached so firmly to the backing that one can work between the tines without scraping off the abrasive. 



I use these on top of sheets of paper. Three sheets give a good amount of cushioning for most smoothing work.

I get my 3M Tri-M-ite mylar papers from jewelers' suppliers, like Rio Grande. I imagine these suppliers would carry metal polishing supplies world-wide.

What's the problem with liquid abrasives? Am I missing something? I was under the impression that they were finer and therefore the final stage. In the old days of vinyl, the perspex lid of the record player would get tiny scratches which would build up into a haze. The solution was to rub with Brasso metal polish. Duraglit used to be the wadding abrasive and Brasso was the liquid, but one firm swallowed the other. Now it's all Brasso, wadding or liquid. (Applies to the UK)

If it is fine enough to give perspex back it's shine then surely it would be suitable for last-stage polishing of a nib? I use it to clean battery contacts.
