Query: Dewalt 10" blades

I have been a Pro. carpenter for over 25 years, bought this combo pack because of the "deal". They are probably the crappiest blades I have ever used, not sharp and splinter the back of the cuts. Both blades were also warped and upon start up made the saw jump. Dewalt has really gone down hill, all of their products are made in China and their hand tools aren't much better than cheap box store home owner tools. Shame on you DEWALT !! Spend a bit more and get a Pro. quality product. Makita makes excellent finish blades as does Freud.
