The Caltrop / Road Spike

FOR STUDY PURPOSES ONLY!


I how to make these road spikes / caltrops during an anti-piracy seminar.


You only need a large carpenter nail, a hacksaw and 3 minutes.


Use the hacksaw to cut 5 cm (or 2/3 ) along the length of the nail and bend the two halves apart.


Now do the same at the other end of the nail, just perpendicular to the first cut.


This particular road spike will always end up with one pointy/sharp end up, no matter how it is thrown.


This makes them ideal for rapid deployment....a cheap and nasty surprise for trespassers!
