Yeah, you can't expect a human to even carry that many weapons, let alone use them. Even elves and dwarves in fantasy novels with their excessive strength and old age are skilled at perhaps 3 weapons at best, and even then carry perhaps 2 at most. Blacksmiths are definitely strong, buuuuut not superhuman strong. 

Plus, chains to bring back weapons... interesting concept, but perhaps quite dangerous to the unskilled. You can easily end up hurting yourself with the weapon you bring back, regardless of the armor you wear. Yeah, just tone it down with the weapons, and stick with 2 at most.
