I don't know Tom Pearson, or his fan fiction writings... but certainly the [multitool] pen "... is mightier than the sword."
That said, I already EDC a sonic screwdriver, in the OEM colors which has nicer anodizing.
(Plus your find has pointy and sharp bits which I might hurt myself with quite effectively.)
Even if I wanted it, the Old Ones have forbidden it. The rumor that I killed many babelfish by attempting to drill their fins and swapping them into my Gerber Nautilus in place of the can opener is ... exaggerated.
Maybe someday if the company can be convinced to integrate a titanium poon.
