This song is the hatchet I wear
And this hatchet is woven from your brown hair

The story:

After singing this song along to the radio confidently for several years, I happened to be belting it out while my husband was in the car. He lost no time in correcting me and now makes fun of me each time we hear the song (I, of course, always wondered why someone would weave a hatchet out of hair, but whatever...)
