I just made one up that is somewhat similar. I added a few extras, put most of the stuff in a couple altoid tins and slipped them into a small zipperd nylon pouch. Good coat pocket kit.
I think if you can spare the room, you might as well add something. I added a diamond honing rod (I can't imagine being lost anywhere without a decent sized knife on my person), a silva matchsafe with compass, a leatherman micra, a tiny aluminum whistle, a ferrocium firestarter, and a wire saw. I substituted water purification tablets for the iodine and used two large quart-sized ziplock bags instead of one sandwiched sized.
Everything fits easily into a 7 1/2" x 6" zippered pouch with room to spare. The pouch slips easily into a coatpocket, backpack, or it has a lanyard clip for the belt. A cell phone case or something similar would also hold it all too.

Hoodoo
The low, hoarse purr of the whirling stonethe light-pressd blade,
Diffusing, dropping, sideways-darting, in tiny showers of gold,
Sparkles from the wheel.
