I came across this blade recently:
It is an 8-tooth 10" blade, part #
Although I am familiar with the general principle that fewer teeth can be used for faster, rougher cuts this blade still seems a bit strange to me. Having only 8 teeth at this size seems especially rough, plus it has the very long arc sections between the teeth which seem like they would add some friction, or at least add no advantage I can think of.
Although on the blade it says "cutting of framing materials, plywood..." I'm a little skeptical of that. For plywood in particular I thought that having a higher tooth count was generally recommended.
So, is this blade for some special purpose or circumstance?
