RileySugarbush,,,,, I remember the brass windshield ice scrapers. Oh how I wish I could find some more. I put them in vice and bend the brass to get more of a straight angle and then 'sharpen' with a file kind of like an old cabinet scraper. They were sharpened square across and then a steel rod was used to roll a sharp edge over.
