Stacked metal gears with engravings

Two interlocking metallic gears, one significantly larger than the other, are depicted. The larger gear exhibits a conical form, tapering to a point, while the smaller gear, nestled within the larger one's base, is cylindrical. Both gears feature a reflective surface and are marked with etched alphanumeric characters. Their construction suggests a stainless steel material, indicative of components used in machinery or mechanical systems.
