I think there are more than two uses of volcanic rock. There are two FORMS of volcanic rock. One is pumice and the other is obsidian. Pumice is often used for landscaping, personal beauty uses (callus removal), etc. The other is obsidian. Obsidian is like glass and ancient people's used it for tools. Knives, arrowheads, and other tools that one would want to have a sharp edge are perfect uses of obsidian. In modern times, obsidian is used for jewelry, art, and even some modern day surgical tools.
