I have many Knipex and Klein tool sets and this type too. This tool is clearly intended for homeowners installing outlets. That's all you really need to do this effectively, a screwdriver, utility knife, and impact tool, and it's pretty neat. Are you replacing your sockets with more stylish versions? Big. Do you automate light switches? Relax. Add an extra 120V outlet outside? Good. Installing an electric car charger? Are you building your dream workshop? Maybe you need more specialized tools. If you do more extensive work - design work, work on the main panel, etc. - this tool is not the most effective. It's better to have a big bag of tricks with you for that. I'm not sure why this tool needs to be run in a sandbox. Homeowners doing odd jobs should probably turn off the breakers before starting work on branch circuits, and I doubt I'll ever put that tool in a live panel.
