You can also get this from Flavor of the Court as I just got a 197 ilvl one.
Dropped out of tribute chest for me at 203 ilvl
Got this from a normal worldquest, but without sockets.
I'm Assassination Rogue, previously these have been daggers in other expansions when called Assassins Blades, so I get two drop of these during my early covenant storyline and I think great, equipped my 'daggers' and DE my old daggers, then realise these are swords! I'm not Outlaw spec, they are called Assassin's Blades FFS, why the *!@# are they SWORDS ! Just in case anyone else falls into this trap, and sells or DE their daggers and basically is back to the stone age weapons wise
