I've been learning to model for a year now on and off and I'm pretty good at making perfect quad organic shapes without any 6 sided or more poles. But I don't know how to make a proper sharp edge to a shape.
On the left, if I use sculpting tools, including smooth, the verts all want to collapse away from the tear edge.
On the right, the verts are stable but I have the undesired 6 sided pole.
How do I properly make this sharp edge shape?
