There is a collection for all exotic dragon blood weapons that gives the title "Journeyman of the Forge"
doing one of the small achievements you unlock after that give "Master of the Forge"
but there doesn't seem to be any collection for collecting all the ascended dragon blood weapons. I hope this is an oversight. The title should be called "Grandmaster of the Forge"
