Yes, I have very strong nails and find I can damage them but not break them so I have to cut them. I usually use nail clippers for this and file any rough edges.
I find if my nails get too long I can't type properly as my nails hit the keys above the ones my fingertips are trying to type on.
I don't normally need to cut them, as they break of their own accord. I only ever cut them with manicure scissors to even them up if they break. Most of the time I have a manicure and she keeps my nails tidy and looking good.
