Color coding your tools can be a big help. Color choice can be artistic, functional, or individual.
Artistic—try World Championship colors: green, yellow, black, red, blue, and white.
Functional—give each size a different color. So your L-keys are faster and easier to retrieve.
Individual—make all your L-keys one color, different from your work mates. When all yours are yellow, for example, chances are lower your tool ends up in their box.
