The term 'marked grooves' can be described as having FLUTED edges. Fluting is a process of cutting or grinding grooves into a surface, usually in a decorative pattern. This technique is often used to create ornamental designs on metal, wood, and stone surfaces. The fluting process creates a series of ridges and grooves that are visually distinct from the surrounding material. This technique is often used to add texture and interest to an otherwise plain surface.
