DualSaw Counter Action Dual Blade Reciprocating Saw

toolguyd.com: There are quite a few circular saws with counter-rotating blades on the market, but what would you think about a reciprocating saw with dual counter-acting blades? DualSaw says that the motion of the two blades in its RS1000 and RS1200 reciprocating saws reduce kickback and vibration. What’s more, they claim that the saws are easier to control, safer to use, and that they produce a smoother cut.
