These blades are the best blades that I have ever used period. The quality kind of made me wonder why I had bought all those other blades for so long. Get a quality blade like this and stop hacking your projects to pieces. From the time you take it out of it's package to the time you cut your first piece you will notice the quality piece you have acquired. Buy one, they work excellently. Buy one from these guys, they ship them out quick.
