Review on DEWALT DW3984 24TPI Portable Blade by Brandon Burnham

I bought a new Dewalt portable band saw and this set of 3 replacement blades. The saw's blade lasted quite a long time, cutting hardened 2 7/8 inch oil field tubing. The new blade didn't make a single cut in the 1/8" and 2" angle iron before the teeth were completely worn out. Since the blade is not heat treated, I will look around for blades from other manufacturers.
