Hello John!

That's a very cool find. But after seeing it I thought: This wire looks familiar! I looked around  on the 'net some and here's what I found:

I'm thinking about buying some like that and putting some barbwire coil on my tanks

Thanks for sharing and have a nice day

nice find I'll probably get some for future builds and dioramas 

Yeah, you can find all kinds of useful stuff at gaming stores! I try to keep an eye open for anything I might be able to use at them, craft stores, the hardware store etc. 

That stuff looks perfect for concertina razor wire! How much does it cost? I have a project that could probably use some.
