Early in my career, as I watched my wandmaker father wrestling with substandard wand core materials such as kelpie hair, I conceived the ambition to discover the finest cores and to work only with those when my time came to take over the family business. This I have done. After much experimentation and research, I concluded that only three substances produce wands of the quality to which I am happy to give the illustrious name of Ollivander: unicorn hair, dragon heartstring and phoenix feather.
-- Mr. Ollivander (Pm)
Used as a wand core (Pm).
Mr. Ollivander considers it a "substandard" core compared to phoenix feathers, dragon heartstrings, and unicorn tail hairs (Pm).
It is unclear just how someone would procure kelpie hair without drowning. The dangers involved might lead to a kelpie hair becoming a family heirloom that the members might wish to preserve inside a wand whether Mr. Ollivander approved or not.
