I was shocked by how long it takes to make each blade. Every carbide tooth individually brazed on, every tooth individually sharpened. And it seemed to take 10-15 seconds for each of these tasks on each tooth. And the manual human hand work required on each blade. I have an 80 tooth cross cut blade. It might have taken 5-8 minutes to make it. I am operating under the assumption this video is representative of how all carbide saw blades are made. Some might be made a little quicker and cheaper I suspect.
