Really like the multitool hands thing going on here. Very good, Very intrigued by how it would feel to have and operate a limb like that. Quite jealous. Maybe go further and just have the whole arm be a mishmash of various tools sensors and fine manipulation arms all meshed together on forking articulated branches like the image on the right but more fractal. Let the various branches lock into place with each other for support if they have to withstand extra force, or unfurl to multitask if that's not needed.
