Over time I've developed a habitual "pocket pat" in which I pat myself down to check all four pockets anytime I leave a building, enter or exit a car, or otherwise go from one place to another. This cuts item loss to a minimum. My wife kids me about how heavy my clothes are considering my usual assortment of accessories -- car keys, "other" keys (on a Leatherman Micra), wallet, comb, small folder (a Schrade, this week), large folder (a Buck crosslock, this week), money clip (I've got a CRKT "PECK" on order to replace my old one), etc.
In recent years I've developed the habit of loading down my briefcase (my "man's purse")with a variety of other items, including my cell phone, a Buck 110 or other large folder, and a Pock-Its utility pouch containing all sorts of goodies, from a miniature pocket hack-saw to a full-sized Leatherman, mag-lite, miniature SAK, ceramic sharpening rod, and Spyderco Ladybug. Between that and all my work papers, schedule book, disk caddy, and usually a book or two, I had to fully expand the expandable briefcase -- and it's getting heavy.
