When i got married i had my Novatac EDC-120p in my pocket, and a spyderco cricket clipped IWB
I say carry it, providing your wife to be doesnt mind. if its small enough she probably wont notice anyway
funny story, i was photographing a wedding the other day, patted my pockets, and found my novatac was missing.
told my wife, and she said wasnt overly happy, was even less happy when i told her that it was the light i carried when we got married (she new i was carrying it, just needed a reminder of the memories attached to the light)
i got home and found it on my bedside table, i hadnt picked it up that morning
was glad that i hadnt lost it though
