The Four-in-Hand is characterized by a simple method of tying and is suitable for almost all ties and types of collar. Small collars in particular harmonize with the long, conical shape of the knot.
The distinctive feature of this knot, invented by the American Jerry Pratt, is that the starting position is "reverse side out". The centre knot is a cross between the Four-in-Hand and the Windsor.
The half or small Windsor involves a simplified variation of the full Windsor. It requires one turn less and is therefore smaller in circumference and more flexible to use with different collar styles.
The double or full Windsor is a classic knot for real gentlemen. It is said to be named after Edward VIII, the subsequent Duke of Windsor. The symmetrical large shape is perfectly suited to widespread collars such as the cutaway.
