Well, Harry is an example where it breaks down then, because he didn't get one, right?
I thought the implication there is that some level of fencing instruction is part of the general Council apprentice curriculum, though I'm not sure I agree. Nobody seems to have been after Harry to teach Molly to fence, for one thing. And we don't know where or when Harry studied fencing to get to his stated description of OK at it but nowhere near good enough to challenge the serious swordsmen. There's never been a mention of whether Justin taught him that, Ebenezar did, or he decided some lessons after leaving Eb would be a useful skill.
In terms of a weapon though, I really can't see Dresden taking up Amoracchius at this point after all the buildup that it has to be meant for someone with the right biblical virtues, even without the WOJ that a sword for Harry isn't in the plan. The Warden of Demonreach has to walk in a lot of grey areas, whereas the Swords are for paladins, pure of heart.
If he's going to get any sort of special weapon, my money is on figuring out how the four of five artifacts from Hades' vault that he already has actually work. Many have speculated the 'knife' might be the head of the Spear of Destiny - if so, the foreshadowing of that being mounted on his staff is, uh, pretty strong. How cool would a showdown between Harry and Cristos be, with Cristos expecting the sword he kept as a former warden to undo Harry's staff, only for Harry to break his sword instead when they come to blows?
