The enarched chief with the blue and silver indentations representing the edge of a saw, in accordance with the ancient practice of heraldry, provides a rebus or word picture of Sawbridgeworth. The indentations also form a kind of dove-tailing, and are allusive to joinery. The two rudders represent the canals and waterways, between them is a wheat sheaf, which refers to farming.
The hart, like that in the County Council's arms, represents Hertfordshire and in order to remove confusion with other similar crests, is placed between two oast houses in allusion to the local malting industry. The garlands of apple blossom typify the fruit industry in the locality.
