The Valknot is the symbol of Odin. It can be described as three entwined triangles that represent Odin’s nature; it’s the knot around a hanged man’s neck, the nine worlds, the nine days Odin hung, the nine valkyries, the nine parts of the soul, and so forth. To wear a Valknot is to pledge yourself to Odin. It is sometimes known as the knot of death and donning it is not to be taken lightly.
I wear a valknot that way when I die, the Valkyries know where to take me.
