Sometimes they can. There’s an example of a cavalry sword in a museum that is covered in nicks. But realistically you aren’t blocking other swords with the edge, but with the flat. And unless you smack the edge into a sharp, focused hard point, you’re not going to nick it. The edges will dull during use, as they cut through armor and flesh, but nicking requires pretty specific circumstances.
