Rubeus Hagrid
A wand is a wooden stick-like object used to channel magical energy and thus increase its power, and without which only limited magic is possible. Wands are used as both tools and weapons in the wizarding world. They are thus an important aspect of nearly all magic, and great importance is placed on wand mastery. Wands are generally carried inside the wizard's robes or otherwise somewhere on their person; however, they can also be placed into other objects. For instance, Rubeus Hagrid hid the broken halves of his wand inside his umbrella, and in the film adaptations, Lucius Malfoy hides his wand in his cane. In the magical world, when a wizard is expelled from Hogwarts, their wands are snapped in half. This type of damage to a wand is nearly irreparable, though Harry is able to mend his wand, which was accidentally broken by Hermione, with the help of the powerful Elder Wand.
