Ken this

Old Norse Kenning for sword: 'onion-of-war', or 'leek-of-war'.

Now use it in a sentence:

'I must be off now wife, for with my onion-of-war I must dice the field-sausages* to use in tonight's bowl-blood**'.

'But enough of Grimnir's lip streams***, friends, for now I must ride-the-cushioned-waves**** with the far-sight***** while battling-with-the-fridge-icebergs******.'

'Why do you trouble me, mother? For I was journeying on the flannel-highway******* to the land-of-pillow-song******** where my onion-of-war would be needed no more.'

UPDATE! - Yes,I don't actually use 'onion-of-war' in the second sentence. I didn't want to. Bah, to hell with the lot of you! I'm going to bestride the flannel-highway once more!
