i seen on an episode this circular saw but also looked like a chainsaw can anyone tell me what kind of saw this is and tha brand?
I'm not sure which episode you refer to but I've seen saws that have the cutting chains similar to what you describe at right angle (90 degrees) to the saw chassis. They are used in timber framing and log home building. If I recall they are made in Europe somewhere.
Just did a "google" and they are chain beam saws. There is even an attacment that can be purchased to convert a circular saw into one.
