I will never forget that miserable ripping demonstration when it happened. The owner of the saw was there. The nails he cut through were sometimes as big as drift pins, and perhaps they were. He shipped the ruined blades to a saw blade repair shop in South Dakota. I imagine that he dropped over a grand to repair them with new cutters or he just bought new blades. I am really glad that you did not have anything like that occur at your thrashing show. Two thumps up!
