So happy to have completed this! It took literally forever. Before the big bang, this prop shield was being created.
Base shield is made of insulation foam with a cardboard rim, completely fiberglassed over (including handle). Then, with a Dremel, I painstakingly carved into the fiberglassed surface to produce both the wood texture (more apparent on the front) and the hammered metal texture seen on the rim of the shield. I got this technique from Volpin Props: [link]
I don't even want to know how many hours this took. But in the end it was well worth it!
