TOOLS
No self-respecting zombie apocalypse survivor should be without the following general household tools:
• A drill
• Screwdrivers
• Pliers
• Snips
• A wood saw
• Scissors
You should be able to find these at any hardware store. To complete the projects in this book, you will also need a few electronics construction tools, listed below.
