While a mullet may have any number of points, it is presumed to have five unless otherwise specified in the blazon, and pierced mullets are common; estoiles, however, are presumed to have six rays and (as of 1909) had not been found pierced.[1] In Scottish heraldry, an estoile is the same as in English heraldry, but it has been said[by whom?] that mullet refers only to a mullet pierced (also called a spur revel), while one that is not pierced is called a star.[1]
The germanic six pointed star looks like this.
