Walnut is widely used in Asia, Europe and the Americas. Walnut can be used for making stock, gun handles and sporting goods. Since the 14th century, walnut has been widely used in the manufacture of furniture, especially in the northwestern European countries. One of the reasons for the popularity of walnut is its light weight and rich color variations. Walnut heartwood is usually light brown to brown in color and streaks that usually vary from place to place. Usually walnut is taupe with clear dark or black stripes, the color of which fades over time.
