Tribulus

[Matt Lukes]

I first learned of this neat little weapon watching a History Channel documetnary about the siege of Alesia, and have since collected enough photos of originals to see just how they're made; and today I gave it a go- here's my result:



A very simple but elegant design- split a short iron bar down both ends, separate the arms to form an 'X', lengthen and pont the arms, then bend one pair of opposite arms (across the X) up, and one pair down, adjusting the angle until you get a tetrahedron.

Not something I'd want to accidently step on...
