I think an even better example are construction tools. Hammers, drills, saws, wrenches, grinders, welders, measuring tape, stud finders, etc. A bunch of these items can be used to break into various secured places and injure or kill someone. But most of the time, they're not, they're used to build or modify things. Most people don't think of a wire testing tool or a saw as a serious weapon and will see the ridiculousness of regulating away ping, wireshark or python.
