I had one pair sharpened by a someone that said he was a sharpener. He ruined them. Unless you know the person has done great work then don't risk it. Scissors use to be a one time buy and the quality ones cost a lot. This is why our grandmothers and mothers treated them like gold. Now scissors are easily made and even the inexpensive fabric scissors are very good. I have my grandmother's dress shears and they are heavy and hard on my hands to use. I think that is one reason she gave up sewing, the cutting was too hard for her with those scissors. I don't use my heavy Ginghers anymore. They tire my hands. I like the new lightweight sharp serrated scissors best of all and they are cheap enough to buy new when needed.
