Ever used a razor blade to scrape something off and then ruined what you were trying to clean? Today you'll learn that there's a new kind of scraper and "feel" that (in many ways) beats blades of steel! New double-edged Scrape Rite plastic razor blades slip into a small plastic holder and look (and scrape) pretty much just like the original steel ones do. However, they don't scratch smooth surfaces, gouge into woods, or rust and corrode like steel ones do. While they do have a tough and sharp steeply-beveled edge which makes them great for scraping, they're not for cutting, which makes them safe for fingers when slips occur. It's one of those "why didn't I think of that?" ideas. Colorful, inexpensive blades just for scraping that don't cut or damage and slip right under edges to gently (and efficiently) remove only what you want to remove (no more and no less!) That's a good thing.
