Hi Robert,

> I cant figure out how he get edges like this:

Check out this other video, it shows the creation of the cutting curves which then form that type of edge result:

One of the main things to notice is how there is some empty space left between the edges (not just "vertical" empty space but also in profile shaping...) , you want to have some empty area for doing a blend because the blend will warp itself to attach smoothly to each edge, if they are sort of lined up with one another that will make a kind of pronounced "S" type pattern. If you want a more relaxed looking shape you need to have some empty space so the blend surface can fill in that empty space.
