Good blades, I bought them with a Porter Cable 20v jigsaw. They cut very well initially, but fade quickly. I used a 2xs Speed Blade to make some cuts and was very impressed. It cut through the wood like warm butter, but after a few cuts it became a little more strenuous to make the cuts. They didn't dull to the point where a replacement blade was needed, but you could feel the cut slowing down. This is the only complaint about these blades. I don't have a control set to compare them and I haven't cut enough with different blades to say they are better or worse than others. Overall these are good knives and I would buy them again if the price is right.
