I don't know how long ours are lasting but the ones we buy are around 200.00. Something to possibly consider....after alot of cutting on a job we did I went to get an extra blade for the hand held saw 9took the table saw blade with me)and the guy asked if I would want the one I brought with me sharpened. Kind of suprised me with that but I let him sharpen it and it was really alomost better than new...I was very impressed by having it re-sharpened,
