Not all display swords are made from stainless steel. The set I have are chromed brass, so they have real weight, but will not hold an edge even though they had been ground to one from the factory. And of course a magnet will not stick either. There are cheaper versions that have aluminum blades. The common tell tale sign of a display sword is the handle grip is made from textured plastic with the cloth wrapping. A real sword would have wood with shark or stingray skin under the cloth wraps.
