Review on Industrial Standard Removing Stickers 1 5X0 75 by Richard Cartner

I ordered these for use around the house, cleaning windows etc and kept a few in the kitchen for occasional use to avoid scalding from grease/food off the glass top. I have a scraper ready for that. When they arrived I still had a couple of single edge blades from another manufacturer so there was something to compare. They don't seem to work as cleanly as the ones I left from another manufacturer. The blades leave something like streaks at regular intervals, as if the edge of the blade is not entirely smooth or wavy. I don't see this being the case, but the blades don't leave a clean area the first time I use the scraper, and I'm hesitant to push the blade further for fear of scratching what I'm scraping. I stopped using them to clean glass plates after seeing the stripe pattern and hesitate to continue using them on window glass or anything that might get scratched. Good price but I wouldn't buy again and would choose better blades.
