Ironwood helped build Penny. She can stop a delivery truck barehanded. Blast and pull A/C out of the sky. They packed a lot of power into a tiny package I mean look at her.

So IF he has a robotic arm in it's regular arm shape it probably can pack quite a punch literally.

Yes I posted the photo of the axe above that was in response to axe or sword.

Personally I'm thinking: Arm as is, changeable into a scaled down version of the spider droid cannon.

Considering Oobleck's thermos. Could it be the more experienced the hunter the more collapsible the weapon?

He probably carries the weapon, or an updated version of it, he carried before the robotic arm, hidden somewhere.
