Anyone know the name of this blade and where i can get it?

pretty much just the title.

Ideas on how to get this item lol

Paragon lvl 224 Deathtrap rogue Capped at lvl 90

Currently paragon level 224, glyphs all lvl 70ish. Still cant seem to get past pit lvl 90. I can attempt 95 but I can't seem to burn the enemies down fast enough. I can tank it all easily but the damage output is my downfall
