The knife and pistol is to make sure no one messes with it and for protection.
I don't blame you I'm heavily armed and have the perimeter surrounded by cameras. With an email alert the instant the cameras on the back of the house sense motion. Some $10 motion detector alarms (hopefully it will scare them, lol). I also have a pitbull, it will make some noise too (which actually don't make good guard dogs but they don't know that)
But who am I kidding my miners are almost a huge box of fans. What would they know to do with it?
