FFS why would they just go around boasting about his healing? They should know more than anyone else that having rare skills like that only bring trouble, they should do everything they can do hide he can do it.
@Kaarme - well, this serrated edge does give a benefit - it paralyzes enemies.
For magic to work, the weapon has to be unusual in some way. Which is why I'm fine with outlandish shapes for fantasy weapons.
