I didn't see much difference in the titanium blade that came with my Fiscars rotary cutter. All fresh blades cut wonderfully for a few cuts and then dull somewhat. The titanium might have lasted a bit longer than the Harbor Frieght ones, but not by much. I also did not like the Fiscars cutter as I couldn't get the nut tightened enough to stop the blade from wobbling. I've gone back to my 20 yo straight Olfa cutter with HF blades.
