The Duo circular saw is the product of the numerous small adjustments and improvements made to current standard sized saws and the Ridgid Dual Blade, which heavily inspired the incarnation of this product. The Duo is aimed at casual DIY’ers. One key feature consists of counter-rotating dual blades, just as the Ridgid Dual Blade, but with slightly larger blades, allowing for thicker sized material boards to be cut. The Duo also reduces kickback, thanks to the counter-rotating blades, which are lubricated by a rod of wax that is fed through a hole located near the head grip.
