Review on Efficient Plastic Razor Blades Scraper Tool For Scratch-Free Paint, Window, And Sticker Removal - 2 Pack With 100 Blades Kit by Enoch Sahay

This is good for light duty scraping where you don't want to use a metal scraper (putty knife or razor blade). I've used it so far on glass, a bathtub (porcelain covered steel), and to clean the underside of my lawnmower deck. Worked well.The plastic blades would wear more quickly than metal, being softer. As you scrape, they form a small plastic burr at the edge, which can be removed.The blades are two-sided, so when one side becomes too dull, you can reverse the blade for a fresh edge.Overall, I am satisfied with this.
