Like Dynasty said, only the Dom Pedro Sword was given out for permanent outside of a Kalika Case.

Given this fact, chances are that a permanent melee weapon is not on Nexon's agenda, for now.

I would guess that the reason why is that people own multiple permanent primaries and secondaries, but a permanent melee weapon is different. With a permanent melee weapon, players would not need to buy another permanent melee weapon.

Maybe there's a chance, but I'm not putting my money on it.
