A cross whose arms end in arrowheads is called a "cross barby" or "cross barbee" in the traditional terminology of heraldry. In Christian use, the ends of this cross resemble the barbs of fish hooks, or fish spears. This alludes to the Ichthys symbol of Christ, and is suggestive of the "fishers of men" theme in the Gospel.
In modern use, the symbol has become associated with extremist organisations after the Arrow Cross (Nyilaskereszt) symbol was used in Hungary in the 1930s and 1940s as the symbol of a Hungarian National Socialist political party, the Arrow Cross Party. The symbol consists of two green double-ended arrows in a cross configuration on a white circular background. The arrow cross symbol remains outlawed in Hungary.
A similar symbol, the Crosstar, is used by the Nationalist Movement, a white supremacist group based in the United States.
