Great list. I also carry
-Emergency bivy sack(fancy space blanket),

-Windproof matches (butane lighter has problems in cold, so I carry both)
Now that I've had the fun experience of getting a fishhook stuck in my thumb, am thinking of adding a needle to my first aid kit....
Wazzu just reminded me of the 11th essential -- duct tape! I always carry it. Oh yeah, a couple of water purification tablets as backup to my beloved steripen.
