Strop care and maintenance

Jim,

There is no such unit as the macron, unless Emmanuel Macron decided to name one after himself. At 5'10", those would be some very large particles.

If .3 micron is real, that's about 80,000 grit which is indeed pretty fine.

For reference, here are the prefixes used in the metric system:

Patiently waiting for some yoctometer sized polishing compound. Perhaps Stewart has a source?

Which begs the question of the paste Stewie linked, is it actually 0.3 micron? Could that be a numeric typo?

Okay, it looks like the Amazon and ebay listing may have two typos unless macron is a tenth of a micron. My Websters says a macron is a dash used over vowels to indicate a long sound.

Found this with a little searching:

Thems be small particles.
