Agreeing with Frank S, sossol, & Inflight; there is nothing revolutionary presented in the GIF; in fact it's not a quarter of full radial arm saw capabilities.
But marketing wise radial arm saws are in the back seat now, ever since tilting, compound and combination sliding miter saws. None nearly as universal; compared to radial arm saws.
However, while OSHA and consumer-protection groups are happier, the ambulance chaser (transporting Darwin Award patients) injury lawyers are not.
