I was looking for the right blade to cut through a series of pieces that needed to be cut as perfectly as possible and when they arrived (e.g. at night) I was glad they were good packaged and well packaged goods looked and felt good straight away. After putting the blade on the saw and making my first cut, I realized these blades are good! Can't comment on durability as I've only just put it on, but I'll say it this way, I've been through a lot of blades and it seems like I got a good deal on. I cut a 2" x 1/4" tubular stock and after about 30 cuts the blade still looked new? WOW
