Salazar Slytherin owned a wand of his own making, made of snakewood and with a Basilisk horn core. The wand had the distinction of being able to 'sleep' when so instructed, an ability taught to it by Slytherin himself. After his death, the wand was handed down the family: by the early 1600s it was in the possession of the Gaunt family.
The wand was stolen by Isolt Sayre from her aunt Gormlaith Gaunt in 1620, when the young girl fled to the New World aboard the Mayflower. Once in America, she used the wand around the time of the founding of Ilvermorny School of Witchcraft and Wizardry. The wand was deactivated by Gormlaith herself when she tracked down her niece and, following her death, the wand permanently wilted. It was eventually buried at Ilvermorny School of Witchcraft and Wizardry where it grew into a unique snakewood tree whose leaves contained powerful medicinal properties.
