Review on OLFA 1086566 Dual Edge Scraper 10 Pack by David Pirlet

These things are incredibly sharp almost to the point where you have to be wearing gloves to get one of these little ones in your scraper. They're precision ground, meaning the entire surface of the blade is almost always in contact with what you're scratching, unlike cheap imitations that have small bumps that make scratching even more painful than it already is. They're surprisingly strong too, I'm still using my first blade and have scraped paint residue off about 25 windows with it, which I highly recommend.
