Smoothing sharp or rough edges on metal things.

Cutting off rusted or rounded off nuts and bolts.

Cutting and/or shaping a few ceramic tiles (Using a "masonry" disk.)

Cutting almost any hard material in a place where you can't fit other tools.

Is is good for use to sharpen mower blades ?

Works for me...

common reason why one is generally better than the other ?
