Jarle drops his revolver, and swings a one-handed ruse towards the Berserker with his sword. As it moves its axe to protect itself, Jarle takes his left hand and slams it, and the Adamantium knuckle duster it bears, into the bottom of the Berserkers jaw. He then drops his sword to the ground, and slams his other fist, with its own knuckle duster, into the Berserkers throat.
