You know what else also carries that? A backpack. All those things are bulky and you usually need a lot available.

Also, no one picks locks unless they don't want it known they were there or don't want to pay for another lock. So ... just use your weapon.

Funny, I was watching a video of a guy with a prosthetic hand. He loved it. He said he went from almost committing suicide to being ok with life again. When he talked about his bionic hand, he said "I'm not left handed, I'm other-handed", as he turned his hand a full 360... It was pretty funny.

That's the use case I was imagining too. Something like in Mega Man, Metroid or Bionic Commando where the arm acts like a super fancy swiss army knife. Seems like something there could be military applications for, or something espionage agencies may want to have available.
