My neighbor and I was talking about this saw a while back when first seeing it advertised on TV, He was supposed to had got one, I need to check back with him and see if he ever did? He is a welder by trade and uses a power hand held Band saw and was a bit skeptical of this new style circular saw and could not figure out how 2 blades running opposite of each other cut take a bite into something, I Have used a circular saw for over 30 years and when a blade gets dull from just cutting wood ya might as well throw it away and go for another, let along cutting through steel

I find it hard to believe to be able to cut like the ad shows, to cut through metal the blade needs to have as fine of teeth can get, although Lately I was surprised while installing some Ipe decking wood, that I was told to use a 16 tooth carbide blade for best cutting, and sure enough it cut very smoothly with minimal splintering
