Here is good cheap ancient way to provide anti personnel defenses. In the picture is a Caltrop. These were used all the way into middle ages and the Ninja in feudal Japan used them as well. No matter how you throw them a point will always stick up. Here is the YouTube link that gave me the idea to make these.
A buddy that I was in the national guard with and worked at the prison together with are going to make a good amount of these and put into storage until needed. This was our first prototype. Were going to make some out of re bar for vehicle stopping. Better to stop or slow down someone away from home instead of on your doorstop. Not a lot of those will be needed I am guessing. The normal size for antipersonnel will be good for its intended purposes but they are also good for depressions that an attacker could hide in as a hasty attack position or other areas that you want to deny an attacker on or near your property.
