4 Inch Razor Blade Scraper Tool Tile Paint Scraper Floor Wall Paper Removal Smoothing Scraper with 10 Pieces Replacement Blades for Removing Wallpaper, Sticker Glue Floor Adhesive 2 Pieces (Black)

I thought I was dreaming when I saw these. As chief cook, maintenence mechanic, and woman of letters, I was choosen to repair the bathroom leaks and grout. Over 45 years, I'm used to being choosen. I noticed that the tile board (which I hate and will be replaced at a later time) had a pall over it. Apparently this is due to hard water and soap scum. IT CANNOT LIVE HERE. I ran out of options for cleaning it and stated to use a razor. That works fine but the razor even with the holder was too small to be practicle. Enter these brutes. They do a fabulous job and save bodily wear and tear. Btw, I created a tool for the grout lines from some household items. I can forsee plenty of uses for these as we , I, remodel the house in my retirement.

The bad thing about it is that on one of them the blade shifted away from the guard while scrapping paint from the floor. It didn't come completely out but, it could have been a bad accident if the blade had broken.
