I've got a chainsaw toothed brush blade for my stihl weedeater and that thing rocks! I can cut down saplings almost 5" in diameter like they are butter. I've got two differnt blades, one with six or eight teeth and another with a bunch more. The one with the fewer teeth works better. The one with more teeth gets too much bite and will try to bog down the weedeater.
Stihl makes good stuff.
