The two main devices (symbols) in the Knotsford blazon are the fusil and annulet. The main tincture (color) is azure.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
The fusil is a shape rather like a lozenge but taller and narrower, hence fusily refers to a field of similar shapes arranged in a regulat pattern. 3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fusil It is though that the shape originally derived from that of a spindle of yarn. Wade believes that the symbol is of very great age and quotes an earlier writer, Morgan who ascribes it the meaning of “Negotiation”. 4The Symbolisms of Heraldry, W.

For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the annulet is a good example, being a circular ring of any colour. They also appear interlaced or one within the other, both of which are very pleasing additions. Wade believes that these were one of the symbols of ancient pilgrims. 6The Symbolisms of Heraldry, W.
