Thurisaz (ᚦ), third rune of Freyr's ætt, carries the name of the þurs — the giant, the chaotic jötunn-force that Thor's hammer Mjölnir was forged to oppose. The Old English Rune Poem declares: 'Ðorn byþ ðearle scearp' — the thorn is exceedingly sharp, harmful to any warrior who grasps it. As the rune of directed, boundary-piercing force, Thurisaz occupies the threshold between the ordered world of the Æsir and the primordial realm of Jötunheimr. It is the reactive defense, the spike on the hedge, the force that guards by wounding.
