Legend says that the islet was named after the Norwegian Baron Kitter who supposedly ruled the Isle of Man.

One day while Baron Kitter was on the isle of Calf, his cook Eaoch of the Loud Voice fell asleep.

Kitter's friends, who had stayed on the Calf, decided that Eaoch had plotted with the witch to kill off the Norwegians and had him brought before the Norwegian-born King Olaf, who sentenced him to death.

It was made by Loan Maclibuin the Dark Smith of Drontheim, and could cut the through hardest granite just by touching it.

However, the witch Ada was there, and told them to lay nine times nine toads' skins, cuirn tree twigs and adders' eggs across the king's legs.
