Small tools tend to be hard to find in a cluttered toolbox or desk drawer. Family Handyman magazine's weblog points out that an inexpensive and simple way to keep such tools organised is by cutting one-inch or two-inch diameter PVC pipe vertically to make simple tool caddies.
You'll want to cut the pipe to length, glue on the end caps and then cut the pipe in half horizontally using a bandsaw. You can screw the bottom layer of pipe adaptors to a drawer to keep them stationary and stack additional organisers on top to form a custom solution for your needs.
