I'm with FreeTrav in minimising powered stuff, but that depends on your definition of 'powered'. There may be some devices that, like plant seeds, are chemically powered, or maybe the knife has some form of self-charger built in, or a nano-clockwork mechanism...
I think the mechanical tools would be made of Crystaliron as a minimum, and probably Superdense. A lot depends on how things are done IYTU. If everything happens online, you'll need computer gadgets, if everything is electronic, you'll need electronic tools, etc.
I'm sure you could get a monowire reel in there, the future equivalent of a USB stick, a programmable universal tool made of a memory metal that can change the shape of its tip, saving weight and bulk, a couple of capsule grenades (hand-primable snub pistol rounds), a pair of superglue/superlube dispensers, and maybe a piezotaser.
Powered devices are more likely to be included in the Scout Comm, the far future equivalent of the mobile phone.
Neat belt-knife, FT, we don't get to see anything like that, they're illegal over here (what isn't?
