Line of partition


The lines of partition used to divide and vary fields and charges in heraldry are by default straight, but may have many different shapes. Care must sometimes be taken to distinguish these types of lines from the extremely unusual and non-traditional use of lines as charges, and to distinguish these shapes from actual charges, such as "a mount [or triple mount] in base," or, particularly in German heraldry, different kinds of embattled from castle walls.

In Scotland, varied lines of partition are often used to modify a bordure (or sometimes another ordinary) to difference the arms of a cadet from the chief of the house.

An ordinary indented is bounded by small zigzags like a triangle wave, with peaks on one side matching peaks on the other. An ordinary dancetty is similar, but with peaks matching troughs, so that the width is constant; it also typically has fewer points than indented. In early armory these were not distinguished. In the arms of the 55th Electronic Combat Group of the United States Air Force the indented is "edged wider on the back angle (sinister) than on the face (dexter) of each angle".

Dentilly is a modern invention, similar to indented, but with one of the sides of the points perpendicular and the other angled, as in a sawtooth wave.

Rayonné (also rayonne, rayonny; from French ) may be considered a variant of indented, but with wavy instead of straight lines, as in the conventional representation of rays of the sun. Rayonne palewise appears in the arms of the 172d Support Battalion of the United States Army.

The arms of the Worshipful Company of Security Professionals contain an example of indented acute, a form of indented with higher peaks.

The number of peaks in indented is almost never specified, but an exception is the arms of Arthur D. Stairs: Per bend sinister indented of six steps Gules and Sable, and Westville, Natal, South Africa bears Sable, issuant from behind a fence of spears in base Argent, a fig tree in leaf Or; on a chief indented of four points to base, also Or, three lion's faces Sable.
