Since the modern is worn mainly as a ceremonial item of dress and is usually not employed for cutting food or self-defence, blades are often of a simple (but not unglamorous) construction. These are typically made from stainless steel. The hilts used on many modern sgian-dubhs are made of plastic that has been molded to resemble carved wood and fitted with cast metal mounts and synthetic decorative stones. Some are not even knives at all, but a plastic handle and sheath cast as one piece. Other examples are luxurious and expensive art pieces, with hand-carved ebony or bog wood hilts, sterling silver fittings and may have pommels set with genuine cairngorm stones and blades of Damascus steel or etched with Celtic designs or heraldic motifs.
