Look on page 14 under NECRON ARMOURY specifically CLOSE COMBAT WEAPONS, which happens to be the only weapon option for the Lord (a CCW, but it replaces the Staff of Light).
The items under WARGEAR are generally not weapons, but if any can be used as a close combat weapon it will be described in the item entry.
But, no, items like the Resurrection Orb are modeled as hand-held but merely serve WYSIWYG (what you see is what you get) purposes.
