The Eberron handbook states that a bone knight is capable of creating bonecraft armor, and eventually even bonecraft weapons. Does this include shields as well? It only lists regular armor in the handbook.
Bonecraft Armor (Ex): At 1st level, you learn to make and wear the distinctive bonecraft armor used by the order of bone knights. You can produce a suit of bonecraft medium or heavy armor that would normally be composed mostly of metal. The bonecraft armor has the same cost and time to create as normal armor of that type. It is possible to spend additional time and money to produce spiked or masterwork bonecraft armor (which may then be further enhanced through magic). Only a character with this ability can effectively wear bonecraft armor.
