The "Strander Knives" I mentioned in a previous thread are used in the oriented strand board industry. A strander has 144 knives placed on a huge disk powered by a 1000 horsepower motor. The strander cuts logs in to 1"x6"x0.025" strands to press into strand board. These knive are roughly 18" long, 3" wide, and 3/16" thick. As I said previously I have access to thousands of used ones and I'm sure they could make stinking big blades. I.K.S. is stamped on them, I should talk to the "engineers" at work, they could have some info for me. Point of reference stranders, are also known as "flakers".
