Noticed some minor updates 
here. Of interest to our audience - on the "allowed" list: 
Tools (seven inches or less in length)
Screwdrivers (seven inches or less in length)
Wrenches and Pliers (seven inches or less in length)
Scissors - metal with pointed tips and blades shorter than four inches
Eyeglass Repair Tools - including screwdrivers.
For what it's worth, my airport carry kit now features the following goodies, all of which make the cut, if you get my drift. 
1 pair of shorty scissors (4" total, pointy)
1 Swisstool Mini-Tool Thingy
1 Pair of Medic Shears
1 Pair of nail clippers
1 6" crescent wrench
I carry an 
empty1 liter water bottle with me, and fill is past security. 
Additional airport kit items you'll like having: 
1. Burt's Bees Brand Bar Soap. It's a shampoo! It's a Shaving Creme! It's a Body Soap! - one bar of soap covers many bases - and it keeps the liquids in your kit to a minimum. 
2. A small towel.  The joke in Hitchhiker's Guide to the Galaxy was "always have a towel" and it's actually great advice. 
3. Money. Don't leave home without it. 
That's all for now. I'm off to Chicago for a 1/2 hour meeting Thursday (really) and I'll let you all know how things are at the frontlines of the whole security process.
