Nice micro kit. Only two thoughts:

First thing I can think of is swap the Coglhans mag block for a Doan's one (they are much less likely to loose your flint rod, Cog uses some less than great glue to hold thiers) or carry a spare ferro rod of some type. And at Bragg, I can imagine you could beg, borrow, or barter for a Doan's (NSN 4240-01-160-5618), talk to the guys who do pilot survival gear, it's standard for most of their kits. Worst case scenario, there are only about half a hundred places within twenty miles of you that will stock them for sale.

Only other thing I might do is put a bit of bi-metal hacksaw blade on there to work as a striker to save your knife blade. If you want to get really fancy, CountyComm.com has a little, folding saw built on the frame of a prep razor, which might not work as good on metal but will work better on wood, and you strike sparks with the spine.
