Gríðarvölr

"Gríðr's staff." The staff of the giantess Gríðr. She loaned it to Thor, along with a girdle of might and iron gloves, because he did not have his own with him at the time, which was Loki's fault. He used the staff to cross the mighty river Vimur. When he arrived at Geirröðr's stronghold, he was shown into a goat shed which had only one chair. When he sat down, the chair suddenly rose toward the ceiling. Thor thrust Gríðarvölr up against the rafters and pushed back hard against the chair, to avoid being crushed to death, and heard a great crash, followed by screaming. Under the chair had been Gjálp and Greip, the two giant daughters of Geirröðr, and Thor had broken their backs.
