Cheese is milk curd, pressed into a form and usually allowed to age. Though not a period heraldic charge, cheese is a period foodstuff, and is thus accepted in Society armory.
Cheese has two depictions in Society armory. The “wedge of cheese” is a triangular portion cut from a circular wheel: it’s fesswise, with the wedge’s point to dexter, by default. The “wheel of cheese” is a disc, with a wedge removed. Both the wedge and the wheel of cheese are drawn in trian aspect for readier identification.
Michael Houlihan bears as a badge: Vert, a wedge of Emmental cheese reversed Or.
Hedewig Sophien bears: Azure, a wheel of cheese argent.
