Ok, does the blade go square at first without a sharp bevel? Serious? On a soil removal tool? You can't remove a thin layer with this blade, it slides over it because it doesn't have a sharp beveled edge. I thought about it when I first got it and looked at it. Also, the bolts are too small for this tool, which vibrates heavily from a large SDS-Max demo hammer. Less than 10 minutes later the nuts and bolts came loose. They are very small for this tool and I am sure they will break if not released. The presence of a wrench and an Allen key for nuts and bolts should have been my first clue. I had to go back and get the real one. I am very sorry that I made this purchase.
