Batonsinister

Baton-sinister, Baton, Baston, Batton, Battoon, Batune, and Fissure are all names used to denote one of the recognised marks of illegitimacy. It is placed in bend sinister, is one-fourth of the width of a bend, and does not extend to the sides of the shield. It will be found occurring both charged and plain, and since the 17th century it has been exclusively reserved to difference the arms of illegitimate descendants of the royal family only.
