Irwin Marathon 10" 24T Circular Saw Blade

When I was looking to purchase a inexpensive, not cheap, saw blade for my table saw I figured I would try this Irwin Marathon saw blade. This saw blade was a sad disappointment. It may appear to be sharp coming out of the package but I had used saw blades that cut better, it left a very jagged edge and rough cut and that was on soft wood. I could not even return it because it had been used. I used it until it wore out and disposed it. Needless to say, this saw blade is a very poor value.
