Characters in the Alien RPG have Signature Items:
"SIGNATURE ITEM: In addition to your nor-
mal gear, you also have a signature item—a small
item that’s not of much practical use, but that has
sentimental value to you and that says something
about your character. Signature items are usually
tiny (see next page) and thus don’t encumber you
at all. Common examples include a patch, a cap, or a
photo of a loved one."
Perhaps "Favored Gear" in the Blade Runner RPG was meant to be something similar?
