A Lifetime Searching: for this scraper!
Updated: Sep 21, 2019
OMG, trying to remove that awful caulk which dries as hard as stone but grows mold like a Petri dish from around my second story windows. Putty knife too weak, double edged scraper broke, enter this puppy: which can be worked with two hands! It even easily removed my blotches from brick after 6 hours. Ah, the right tool...
