A fully moddable techblade drops of the last heroic of the belsavis bonus series level 44 i have 2 of them one i got off the GTN and the other i got from a drop, happy hunting.
Please don't post misinformation. This is completely untrue.
A.) The belsavis bonus series is lvl 50 only.
B.) The quest in question gives an option to choose a lvl 50 moddable version of every single companion's weapon EXCEPT for Techblade wielding characters. In which case their weapon is a lvl 50 blue unmoddable item.
It really irks me when people troll like this.
