Symmetry looks like brass handle but head is zinc, it also looks like similar head like the razorock jaws and Magyars open comb head, should be medium aggressive razor. It also cost 30+ after shipping.
If u want to go as cheap as possible and try aggressive razor then get the maggard v3a head, it's awesome a small notch below the grande in agressivnes and cost 11 bucks shipped.
If money is no issue then hands down brass razor is the way to go, if u want aggressive then fatip grande, if u want medium aggressive then fatip gentile. I have both and they are great shavers, left u pic earlier of both one in gold and other in gun metal black. Ur money ur choice
