"Stinkbug" Device Concept art (Patreon)

Chet is getting a device to use in combat, called the "Stinkbug", it's worn on a person's back and exudes gas of the user's choice. They also get a pair of butterfly-knife-like shears.

I am stuck between making it dispense gas through a handheld rod, that then can be attached to the device's back when not in use.

OR a gauntlet that goes on the user's hand.

Aesthetically, I like both. The rod could allow for a fun animation/scene of them attaching it to the back before taking out knives. The negative is that it might look too clunky/big for a character thats supposed to be nimble and slick.
The gauntlet goes along with the "arm" theme thats going on in Pro Soc,, everyone getting hand-related weapons. The negative is that a gauntlet would look too clunky to wield knives/shears with,,, (ideally I want the gauntlet to be big and fat cuz,,, thats more aesthetically "steampunk gauntlet")

Both have potential for cool imagery hmhmmhh---
