There is a drawing of a hammer, that resembles an upside down capital letter "T""All About Odinism- Your Questions answered."
The bottom lines follow that symbol.
From the literature we can see that Odinists in ancient times incorporated this symbol into their liturgies, using representations of it to hallow new-bom children, to bless wedded couples and to sanctify the funeral pyres of the dead. We also read of the sign of the Hammer being used to consecrate libations offered to the gods; and it was frequently worn as an amulet or pendant, many such finds having been discovered by archaeologists. It is, above all, a sign of divine protection and hallowing, by which we demonstrate that we have become allies of the Æsir in their struggle against the forces of chaos.
Odinists also nowadays often sign themselves with the sign of the Hammer in the course of celebrating their rituals. This is done by clenching the right hand in a fist (indicating strength and determination), raising it to the forehead, and then tracing the sign of Miollnir, in the shape of an upside-down 'T', by moving the fist, first, to the sternum, the mid-point of the chest, and then to right breast, and then to the left breast, while reciting the words:'In the name of the Æsir: and of the Vanir: and of all the Powers: of Asgarth.' The symbolism of this action can be explained as follows: Showing strength and determination, I shall honour the gods with all my mind (indicated by the forehead) and with all my heart (the sternum), from the rising of the sun (that is, from my earliest years), which is indicated by the East (i.e. the right-hand side, when facing towards the sacred point of the North), until the setting of the sun (that is, until my dying day), which is indicated by the West to the left.
