Well, while working at the forge today I grabbed those two broken pieces and normalized one, while leaving the other as a control. After three cycles of successively lower heats I brought one piece above critical and quenched it, then broke it with a hammer. Lo and behold, the grain structure was small and silky smooth. I'm amazed, they don't even look like they are made from the same material. I was worried that just eyeballing the color would not produce good results on normalizing, but wow was it much improved. Thanks for all the advice.
