NUARM Prosthetic Limb

A character in my upcoming Scifi short has an amuputated arm and thus requires a very interesting prosthetic. The prosthetic in question is this: The Neural Uplink Assisted Relay Manus, or "NUARM". This military model of the NUARM can interface with all military equipment magnetically for virtually normal use, i.e. it gives the user short range metal-centric telekinesis. I've always wanted one of these.
