No your hero weapons are not tradeable sadly, yes he did say they would be but surprise surprise he lied to us again. If they were tradeable it would have made for a very cool online collectible, trying to get a heap of hero swords that other people had created would have been great. I think the reason behind this is because you only get one set of hero items. You also cannot sell them even though they are given a value in the menu, possibly just to tease us.
