The walnut tree is a hardwood timber that has been frequently used in woodworking workshops. Generally, its wood is tough, heavy, and durable. However, it is pretty easy to work with the walnut compared to other hardwoods. It can be effortlessly bent and twisted thanks to its flexible structure. The smooth surface of the walnut wood facilitates the varnish and painting process. In addition, it is also good at connecting with nails, screws and glue. The walnut wood also gives successful results in carving and turning works. It has a rough structure when it comes out of the factory, but it becomes desired shape by grating on the planing benches. The walnut wood can also have a satin-smooth surface with the oil applied to the surface after sanding.
