In order to get a free Lenox reciprocating saw blade, simply click on the T2 Test Lab and Warehouse links at the top before finally hitting the free blade link in the lower left. You may also want to like them on Facebook, but I'm not sure if that's required.
When you load the final page, it says something along the lines of “there's no such thing as a free lunch, but how about a free blade?” Oh yeah? I accept your challenge. A dash of hot sauce, a little pepper, and I'll be able to eat that saw blade in no time. Plus my dentist mentioned business is slow, so it's win win for everybody!
