A simple medallion of my logo. As well as a good looking pendant, this functional jewelry can be used with paracord in an emergency as a cental point for multiple strands. Rescue netting and tarp elevation are common uses of this technique. The stronger materials will carry more weight in such uses. In this case the most coherent material is the cast brass, although sintered steel is still quite strong.
Gold and Silver varieties, probably less useful in that function, just to warn you.
