Well with a better phone he could eliminate the Psion 3mx organizer as most phones now a days can do anything one of those little organizers can.
replace his DMM with one that has a battery test mode to eliminate the battery tester. The electrical tester screwdriver isn't needed with the DMM.
If he switched his flashlight to an AA powered one instead of those 123's he could eliminate a few spare batteries. He has 4 bettery powered items I counter, the razor, camera, flashlight and DMM, standardizing on one type cuts down on spares.
Perfume is unnecessary and unless hes frequenting singles bars (too many people now a days think they need to wear it to work or the grocery store or wherever).
