The zulfikar is a charge from Islamic heraldry, representing the sword given to Ali by Mohammed (on whom be peace). It’s depicted as a sword, whose blade is strongly forked for about half its length; the blade might be either straight or curved. The zulfikar shown here was used on the standard of Selim I, Ottoman Sultan 1470-1520 [from the Topkapi Museum, Istanbul].
The Society’s default for the zulfikar is that of the sword: palewise, hilt to base.
Gürcü İskender bears: Azure crescenty argent, a zulfikar inverted Or and a gore sinister argent.
Jethro Stille bears as a badge: Gules, between the blades of a zulfikar inverted a mullet of six points Or.
