Ninja Caltrops

These are pretty cool. Won't work very well with people wearing shoes that have a thick sole, but will work great against anyone barefoot. They aren't expensive and worth the price.

When I saw these on line I read about how these were something used in the James Bond movies, wow. They are something I have never used before. I started practicing using these and I can only get better. These are very easy to use and great quality. I would recommend these to everyone.

These are pretty good stuff. Will tell you, they won't be strong enough to puncture a cars tire, but will be enough to stop or slow down an attacker. I like that they are small enough to fit in a small hidden pocket. Only gets 4 stars because I want them to stop a car tire, but what can you expect for 3.95. Still, a good deal for a good product. Make sure you buy at least two packs
