Mike H, 
The Gossman PSK is a small fixed blade knife.  
Buffalohump, 
You are missing your own compass and map of the area.  Don't assume that you will always be together, a compass is a pretty basic nav tool and many survival situations get a kick start from people (experienced or not) getting lost.  I take a small Garmin (Geko 301) GPS too, but that's just me.  I don't see a signal mirror either.  
DR's PSP is a good thing to have and it contains the  mirror, but the button compass in it should be a back-up.  A good   
sighting compass like a Silva Ranger or Suunto MC-2G would be on my list.
