Cross Bow Knot
This is a way of slanting the angle obliquely and tying the Bow-knot. It is one of the most common knots seen from the late 19th century to the early 20th century.
There is no definition of "how much you should slant", but we separate it from Basic-bow-knot because it gives a distinctly different impression. In recent years the designer Karl Lagerfeld used this knot-way for his bow tie.
