I think I paid less then 10.00 for this blade. I've been paneling my man-cave (enclosed patio) the past week and this saw blade has been indispensable. I bought it for my Black & Decker Firestorm Cordless Saw and wasn't sure it would fit. The blade fits perfectly, but just remember the direction. Initially, I put it on with the print facing out - oops, wrong direction. The direction of the arrows indicate that the print side faces in and the bare blade faces out. I cut several sheets of 5/32" thick, 4' x 8'  MDF (hardboard) panels to cover the frames around my windows. The blade cut smoothly and did a great job.
