Hey kids! I found this out the other day when I was about to tackle a huge coralline scraping job and couldn't find either of my plastic scrapers. I went out to the garage where I have one of these babies hanging on my peg-board. Decided "what the heck" and pulled out a new blade, wiped it off and went after the coralline. To my shock, the coralline came off like it was a post-it note.When you're done, you can try to rinse the blade and keep it, or you can just toss it because you have a pile of them.
Anyway, here's what I was using, or a reasonable facsimile. I bought a cheaper version at Menards than the Stanley ones.
