how lawn mower blades start getting dull after only cutting grass.

Question

Say you’re a lawn mowing professional or just your regular average ol homeowner, but you’re extremely careful and never hit rocks or damage the blade in any way. The mower blades still get dull, with only blades of grass and grass is not a hard substance. How does something soft like grass, dull a lawn mower blade?

No one is really that careful with their lawn mower. Especially where the grass meets any kind of concrete surface like the driveway or sidewalk or street. And the roots of trees can damage lawn mower blades too.
