Ninja Caltrops

So, you wanna be a ninja? Well heres something you might need.

"Caltrops" - A caltrop (calthrop, jack rock, star nail or crow's foot) is a weapon made up of two (or more) sharp nails or spines arranged in such a manner that one of them always points upward from a stable base (for example, a tetrahedron). Caltrops serve to slow down the advance of horses, war elephants, and human troops. It was said to be particularly effective against the soft feet of camels.[1] In more modern times, caltrops are used against wheeled vehicles with pneumatic tires. In Japan such devices were known as makibishi.

Gotta Get them camels!

Materials: Scissors and a peice of sheet metal about 1" X 2".
Actually the size doesn't matter but I like this size.

Or if you are using thicker metal use tin snips

Here is where the scissors are needed.

Cut 2 lines length wize from each end about 1/3 of the way (see picture)

Now

Cut from the... just look at the picture

You want the final out come to look like a squished hour glass

Here might be the hard or easy part. If you have thick sheet metal then find something curved and hammer it into shape.

If you got thin metal from a pop can or what have you then you can just bend it with your fingers.

Postition the metal so the hour

Now! Throw it on the ground and it will always land with a point up.

If you made it with thin metal it will probly only hurt people with no shoes but if its thick you'll be ripping TROUGH CAMEL FEET!
