Do twin-blade circular saws reduce tearout?
I purchased one of these dual blade circular saws and to be honest they are no better than the persons talents using any power tools. Save your cash to buy the best quality saw that will give you the ability to do anything you want. My best investment to date in circular saws was my worm drive. It is heavier than others and needs more room but it doesn't kick back and has the power to cut anything I put in her path.Everyone has to try everything themselves so try to find someone who owns one and will let you try it out, plunge cutting is their major asset but this is no problem with my worm drive either  ;) :)
