The half Windsor knot is what I would like to refer to a semi-formal knot, which works well on casual and formal collar styles alike. It is unknown how this particular knot got its name since scientifically speaking it makes up only one third of the full Windsor knot.
I personally like to use this knot on formal collars style. Although on the cut-away collar this knot is generally avoided because of how it appear can appear unsymmetrical. However this knot applied would suggest the wearer is making a style statement of self assurance and confidence.
How to do a Half-Windsor knot:
1. Ensure the front blade is longer than the back blade when placing around your neck. I can not stress the important of this, as the appropriate length will allow the front blade point should rest on or above your belt. This will vary depending on height of wearer, so practise and test. As mention in my last post (How to do a four in hand knot) if the blade goes below this point it will draw unnecessary attention to your crotch giving a subliminal image of the male member, which is extremely inappropriate.
2. Cross the front blade over to your left over the small blade.
3. Put front blade through the neck noose.
4. Place the front blade over to your right.
5. Now place the front blade under the back blade to create the foundation of the knot. Depending on how tight you make this part will determine the shape and size of the overall knot. Therefore with a little experimenting you will be able to test and see for yourself which shape you prefer.
6. Conceal the foundational knot by crossing the front blade over.
7. Pull front blade through the neck noose again.
8. Finish of the knot by pulling front blade through the knot noose and adjust as you feel fitting.
And that's how you do a Half Windsor knot.
