It can be really difficult to get good photos of a mint condition blade, and I don't have any stock photos of cast blades. But here is a photo of the eagle on one of the House of Swords blades. Notice the wings are made from small block pieces, the design of which were cast into the blade. Also note the crude eagle head and the blocky "E PLURIBUS UNUM" that is also cast in the blade.

In contrast, here are two etched eagles from a couple of my officer's swords. Notice the intricate designs are done with etched fine lines.
