In Norse mythology, Gambantein (Old Norse gambanteinn 'magic wand') appears in two eddic poems.

In the Hárbarðsljóð (Stanza 20) Odin says:

A giant hard       was Hlébard, methinks:
His gambantein he gave me as gift,
And I stole his wits away.

In the Skirnismal (Sanzas 25–26) Skírnir speaks to Gerd:

Seest thou, maiden,       this keen, bright sword
That I hold here in my hand?
Before its blade the       old giant bends,—
Thy father is doomed to die.

I strike thee, maid,       with my gambantein,
To tame thee to work my will;
There shalt thou go       where never again
The sons of men shall see thee.

Skírnir then condemns Gerd to live lonely and hideous, unloved, either married to a three-headed giant or forever unwed. It might seem that this gambantein also refers to the sword which which Skirnir has previously threatened Gerd. But immediately after concluding his curse, Skírnir says (stanza 32):

I go to the wood,       and to the wet forest,
To win a gambantein;
.   .   .   .   .   .   .   .   .  
I won a gambantein.

The poem then continues with further threats by Skírnir condemning Gerd to a life of misery.
