NASA's More Obscure Lunar Research 59

Or how good the skiing is there?
If you do decide to hit the lunar slopes you may want to take a torch with you in case you run into your own shadow."

Water and wind to be specific. All that tumbling around takes the sharp edges off the sand grains.
I imagine the sand/dust on Mars will be closer in quality to the sand & dust on Earth, than the Moon's.

Your are right to point out, though, that this eventually ends up in rock again in some form or another. And this rock gets exhumed and eroded into big particles, some of which may break further down to sand, silt, clay...
So the answer lies in the fact that on earth, additional large debris is generated along with fine debris. On the Moon, it's the same stuff sitting around getting hammered over and over by meteorites. It ends up very fine and very pointy.
