Tie knot/material/construction/technique question

[Musicled]

This might be very obvious to most of you, but since I left the great state of Texas I'm not as connected to the sartorial cognoscenti to help answer the questions that do pop up from time to time.

Therefore, help a guy out.

I've seen a few knots that are plainly works of art but I can't seem to replicate this certain one and it's been bugging me.

For example, Ron Rifkin in the TV show Alias frequently used this compact, roundish yet remarkably pinched at the bottom kind of knot. I'm sure it was a full/half windsor but nothing doing. Can't manage to make it happen.

The ones I'm referring to are rounder and more pinched than the one in the link.

Any ideas?

Thanks in advance,

Eric
