The main device (symbol) in the Hammencourt blazon is the mallet. 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) 1. In a sketch or drawing it is represented by plain, unmarked paper 2.
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 3. 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 4. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 5.
It is important that a coat of arms be easily recognised and so everyday objects were frequently used as clearly identifiable charges – tools 6 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 7, let alone know what to use it for! The hammer is usually drawn conventionally, with a wooden handle and large metal head. 8
