When Harry Potter buys his wand, Ollivander asks him if he is right or left handed:
"Well, now — Mr. Potter. Let me see.” He pulled a long tape measure with silver markings out of his pocket. “Which is your wand arm?”
“Er — well, I’m right-handed,” said Harry.
Ollivander's question implies not all wizards are right handed, which brings me to my question: Are there left handed characters in Harry Potter? (Either described as such in the books or portrayed as such in the movies.)
Edit: The reason I ask this question is that I know two girls who like role-playing in the Harry Potter world, and one of them uses a franchise wand (I guess, it is Hermione's) and the other (who is a leftie) says that she finds it uncomfortable to use… So I wondered if the story would give some reason to produce franchise wands for lefties. So, this question is not about left-handed monkey wrenches…
