Do twin-blade / Twincutter circular saws produce a more accurate cut than regular circular saws? Do they have less kick-back? Do they reduce the tearout / splintering / chipping at the rear of the cut, compared to regular, single-blade circular saws? I'm looking for real-world experience, as I've seen countless sales-pitches on the matter.

The Twin-Cutter circular saws have two circular saw-blades spinning in opposite directions. It behaves similar to a regular circular saw, except with a slightly wider kerf (since there are two blades), with aparent benefits. Here is a sales pitch video on YouTube

Some additional articles which I find inconclusive:

I think the real place where this tool is useful compared to a traditional circular saw is for plunge cuts. I can't imagine where this would outperform a regular circular saw for a non-plunge cut unless you had tight access that a smaller twin blade could get into.

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 ;) :)
