Ivory tools are implements crafted from ivory, which is a dense material primarily derived from elephant tusks, but can also come from other animals like walruses or narwhals. Historically, these tools have been used for various purposes, including carving, writing, and crafting due to ivory's workability and durability. The use of ivory has significantly declined due to ethical concerns and legal restrictions surrounding wildlife conservation and the protection of endangered species. Today, alternatives like synthetic materials are often used instead.
