a shakefork is also known as a pall
and a pairle
. It is a Y-shaped division of the field of a shield, like an inverted chevron
descending from the upper edge, with a foot extending to the base of the shield. It is very rare in English heraldry but more common in Scottish
, particularly in the family of Cunninghame
It is more usually, though, not always, cut off just before it reaches the edges of the shield.
