ERASED

In heraldry, erased describes something represented with jagged and uneven edges, as is if it has been torn off. The term is particularly used to describe the depiction of a head of a beast. If the charge is a small tree branch, appearing as though torn off, it is described as slipped, while a large tree branch depicted the same way is described as snagged.
