I often supply various tools to the job site to be used by workers, who for some reason, never show up to the job with the proper tools. Brooms, shovels, various hand tools are used by others. In order to get these back in my truck, as opposed to one of their trucks, I spray a little day glow paint (as used by surveyors) on each tool. At the end of the day, I can ID my tools and round them up easily.
