How sharp do atomic force microscope tips have to be?

Smaller and sharper gives better resolution, but maybe wider and blunter gives more force?

Sometimes they are atomically thick or wide if there is a whisker acting as a tip, but this tends to be angled and not very repeatable. More often tips are coated, which often increases the radius of curvature to more than 10 nm.

...wider and blunter gives more force...

Are you trying to crush something with your atomic microscope?
