Night Blade/Gloaming Blade

Hello,

While i was checking some rogue dagger transmog in youtube, i saw these daggers, Night blade and Gloaming blade. Just curious if they are obtainable on this server because i can't seem to find them in the Store. It says on WoWhead that some mobs in Black temple drops the Night blade. But i've been farming the Black temple for couple of days now and didn't had any luck.

Do you see the drop rate on wowhead? 0.02% from one mob and 0% from rest good luck with that , but for gloaming blade you need to pick pocket the mobs in pandaria, so good luck

Thank you, sir, for the words of encouragement.
