Review (5/5): One of those tools you need more than you think
For years, I would simply just scrap off various residues with whatever I had on me: a knife blade, my finger nails, a flat head screw driver, a bare razor blade, etc. But after I needed to work on removing some sticky residue from a large pane of glass, I finally picked up a scraper. It's a simple tool, but it does the job well. The razor blade does most of the heavy lifting for these types of projects, but having a proper handle that safely locks into place is a dream and it makes the scraping process go from 0 to 60 in one second.
