I EDC an altoids tin with:

needles (2 thick and 2 curved and 4 regular)
20 ft thread (black)
Fishing line (50lb test about 30 ft mostly for thread or cordage)
Back up red led flashlight (micro handmade by me)
8-200 mg ibuprofen
4 bandaids (cloth)
4 Iodine wipes
Vial of OralGel
4 q-tips
2 2x3 gauze pad
Sport tape
super glue
1/2 roll of gauze
Razor blade
Duct tape
4 heavy rubber bands (different sizes, thicknesses)
5 Safety pins (from little brass to a big one)
Little piece of picture wire
2 copper wires
Can opener

Mostly I carry stuff that I have said "I wish I had..." My kit is designed with the attitude that I will use/need these things often enough that it warrants carrying daily. I just consolidated into the tin so I am still testing to see what stays/goes.
