I have created a curved line with an end anchor point - the top left end of a horn, in this case, and lost one of the two bezier curve handles. I want to get that handle back without losing the curve created by the other side of the handle.
See image. The left corner has a top bezier handle, but I've lost the bottom handle. I want to get it back without losing the curve of the top of the horn. Hopefully I'm making sense?
