Elastic wood is a type of wood that is known for its flexibility and strength. It is often used in furniture, musical instruments, and other items that require a strong yet flexible material. The two most common types of elastic wood are YEW (3 letters) and ASH (3 letters). YEW is a hardwood that is native to Europe and Asia and is known for its strength and durability. ASH is a hardwood that is native to North America and is known for its flexibility and shock resistance. Both YEW and ASH are popular choices for making elastic wood products.
