The saltire, whilst frequently associated with Scotland is actually a widely used and popular ordinary found throughout all of British Heraldry, perhaps because of its cross-like form Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 42. In order to allow for clear differences between similar arms, heralds designed a series of decorative edges, not all of them are appropriate for the saltire (because of the interior angles) but those are suitable can be very effective artistically. The pattern engrailed works well here. It is a series of scalloped indentations with the points facing outwards – and should not be confused with invected, which has the points facing inwards! Wade believes that both of these indented forms represent “earth or land”, and one perhaps can indeed see the furrowed earth embodied in them.
