Avoid losing tools in the fields or forests ...

A few years ago when I was working in the back country my handgun slipped from the shoulder holster and dropped into the leaves and underbrush. Not only was the gun a gift from my son, it was among my all-time favorites. I learned through some tense hours of searching for it just how invisible even brightly reflective metal can be in the shadows and shapes of a forest floor. Since then I've kept a bright ribbon tied to the trigger guard.

Such a trick is also good for other tools that are used in out-of-the-way places. See, for instance, how I keep from losing log chains at this link.
