So if it's not as rough as I really wanted why did I give it a 5? I am very impressed with the quality and the price. I needed to increase the spacing between some cement blocks in a foundation project and they are too good for that, but I won't judge them for my desire if they are impressive on their own. They're cutting cement, just too slow for my needs. They left a nice smooth slide (which I will fill with grout). I'll hollow out the cement with something else, but I'll leave them somewhere I can find them next time. I carve someone's name on tile or granite.
