I mean, he's had this 'hammer/axe' complex forever (since book 1), he's had this 'lord/blacksmith' complex forever (since book 4), and all of his handwringing about everything, and in fact his entire characterization up to this point, is perfectly represented in the act of him blacksmithing the very thing that's the most obvious symbol of his lordship, as well as something that can be used to create or destroy. He's got his shit together finally, in time for the last battle. I thought it was perfectly appropriate, and not only that, pretty enjoyable to read.
