Odin’s ravens: Hugin (thought) and Munin (memory) fly all over Midgard to bring information to the Allfather.
The Valknut (coined from Old Norse valr, "slain warriors" and knut, "knot") is a symbol consisting of three interlocked triangles. It symbolizes the power of Odin to bind and unbind the mind, unbinding his chosen warriors from tension and fear while binding his enemies so they become helpless in battle.
The ring is made of 316L stainless steel, a nickel and molybdenum alloy known for its sturdiness and corrosion resistance. A ring to last a lifetime.
