The Triple Horn of Odin is a stylized emblem of the Norse God Odin/Woden. The horns figure in the mythological stories of Odin and are recalled in traditional Norse toasting rituals. Most stories involve the God’s quest for the Odhroerir, a magical mead brewed from the blood of the wise god Kvasir. This symbol consists of three interlocked drinking horns, and is commonly worn or displayed as a sign of commitment to the modern Asatru faith.
This is freakin' AWESOME! Mjolnir with the wolves Fenrir (son of Loki - will slay Odin at Ragnarok), Skol (chases the chariot that pulls the sun across the sky), and Hati (chases the moon). My inner Norse mythology geek is showing again, huh?
