I have a small sewing kit, with tiny scissors and recently went EWR-CDG-NCE. In the US, I wasn't stopped, checked or questioned. In Paris--they did ask to see the 'item', and after a brief consultation--decided they were fine, and let me keep them. On my return, in Nice again no problem-and in Paris they didn't ask me to open my bag, just questioned what it was, then sent me on my way!
