So uhh...

Doing a gesture makes them appear equipped o-o;; that's normal right x.x?

It's a glitch caused by the Knuckles penetrating the gloves. The same can be done when using Open Umbrella before a gesture, partner action, or persona.

so when sheathed, they shouldn't appear at all :c? what a bummer...wouldn't mind wearing champion knucks while running around with a machete o3o;;

You can glitch them into appearing. What you want to do is pick up your knuckles from being equipped, press the switch weapon tab button, right click to put them back on the now sheathed slot, and they'll now appear equipped to everyone who was in the instance at the moment. And yes, this includes while wearing other weapons.

neh...it sounded better in my head...
