fiddleback

Flame maple (tiger maple), also known as flamed maple, curly maple, ripple maple, fiddleback or tiger stripe, is a feature of maple in which the growth of the wood fibers is distorted in an undulating chatoyant pattern, producing wavy lines known as "flames". This effect is often mistakenly said to be part of the grain of the wood; it is more accurately called "figure", as the distortion is perpendicular to the grain direction. Prized for its beautiful appearance, it is used frequently in the manufacturing of fine furniture and musical instruments, such as violins, guitars, and bassoons.
During the westward expansion of early settlers and explorers into the lands west of the Appalachian Mountains, curly maple was often used for making the stocks used on Kentucky rifles.
