1. When forging, would it have been more feasible to forge the flanges as one piece with the tang or to weld them on afterward? Would the latter leave them prone to delaminating?
2. If one made a replica by cutting and grinding a blank from steel plate, would it make sense, again, to weld flanges on? Or, even assuming such construction would be strong enough, would doing so bring the cost up so dramatically that you might as well have it hand-forged?
