I am not an expert, but I think the teeth of the saw 3 is called "Shark teeth". In any case, all 3 super sharp and I'll have to practice a bit to get really good thus to arrive at right. The hand saw I could quite successfully saw 19mm multiplex. It was cut very clean and I found it easy to stay on "line". Perhaps for "professionals" only gimmick -> absolutely sufficient for me, since everything is done anyway on machines with larger work.
