Once, Parashurama  visited Mount Kailash, the home of Shiva. Shiva was then asleep, Ganesha stopped Parashurama from awakening his father. Parashurama threw his axe angrily, which he had got from Shiva, at Ganesha. Ganesha recognised his father's axe and received it with respect. The axe cut one of his tusks. Since then Ganesha is called Ekdanta, which means one-toothed.
