How sharp are the bits of sand and rock on mars?

Space Exploration Asked on December 26, 2021

Lunar regolith is quite sharp, so abrasive it can cut kevlar.

This is because there is no flowing water or substantial atmosphere to erode the material and smoothen it out, so meteorite impacts break it up even more, and it stays sharp like broken glass.

What about mars? The martian atmosphere is somewhat substantial, at almost 0.7% of the earth’s in terms of pressure, and there is quite a bit of wind too.

How sharp are rocks and the regolith on Mars?

Please compare it to the earth and the moon in your answer.
