In the collection of tools I got with the Uni Saw I bought from an estate I have a Craftsman 9 in. 8 tooth carbide tipped blade. I have never mounted it as I have no idea what it is designed to cut, Why would I use it. I punched the description into Google and Amazon figuring someone trying to sell one would tell you why you need an 8 tooth blade. None came up, none at all. Anyone know? For cutting logs?
