The four main devices (symbols) in the Hamerton blazon are the hammer, chevron, trefoil and lion. The two main tinctures (colors) are argent and sable.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 1Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 4Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
It is important that a coat of arms be easily recognised and so everyday objects were frequently used as clearly identifiable charges – tools 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 69 being a common and important example of these, of which the hammer is typical. Some of these tools are rather obscure to modern eyes, who of us nowadays would recognise a hemp-break 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P163, let alone know what to use it for! The hammer is usually drawn conventionally, with a wooden handle and large metal head. 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Hammer
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 9A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.10The Pursuivant of Arms, J. R. Planche, Hardwicke, London 1859. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 12A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. The trefoil may originally been a representation of a specific plant (perhaps shamrock) but it has been used as a symbol almost since the beginning of heraldry and over time has adopted a stylised aspect. 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Trefoil. Guillim believes that it signifies “perpetuity…the just man shall never wither”. 14A Display of Heraldry, J. Guillim, Blome, London, 1679, P109
