There are only two knots that I know, the Windsor and half Windsor. I typically use the Windsor unless the tie is too bulky. Most of my collars are spread so that works well for me. One of these days I will stand there in front of a mirror with one of my Dad's bow ties and keep tieing it untill I get it right. Of course, I don't have one myself right now and his are all the old narrow ones from the '50's that are about 3/4" wide at the tip.
