I am not familiar with these blades so I don't know what to expect re: the cutting edge. There is no bolt on edge like I have on my 1650 blade. As part of the manufacturing process the bottom of the blade seems to have been folded over to the rear of the blade, then rolled back forward to create a triangular section that is then stitch welded to the back of the blade. The bottom portion of this triangular section is partially worn through from being pushed over pavement.
