Scroll down to see a hi-res pic of Richard Armitage as Thoren Oakenshield in The Hobbit films.
The pic comes courtesy of CB Swords, and they even have a detailed description of Oakenshield’s sword, Orcrist. You can read it here:
In Third Age of Middle-earth, Thorin Oakenshield and his Company of Dwarves came upon a troll lair in Rhûdaur. There Thorin found an ancient Elven sword named Orcrist, forged by the high Elves of the West, in Gondolin. Thorin claimed Orcrist for his own and vowed to cleave Goblins with it once again. He wielded the sword through most of the Quest for Erebor, using it against the Goblins of the Misty Mountains. The Goblins called it “Biter” and hated and feared it.
The blade of Orcrist features a curved leaf shape on one side, and a straight edge on the other, a fitting design for a blade meant to cleave Orcs and Goblins. Adorning the pommel is an emblem of the heraldry of Ecthelion of the Fountain. The hilt is shaped from the tooth of a dragon. It is unknown if the tooth was acquired prior to the fifth battle of the First Age, or added to the sword with the inscription in the millennia after the Fall of Gondolin, most likely by the Dwarves of the North.
The Hobbit: An Unexpected Journey hits theatres December 14th.
