Silky Saw - Folding Saw

There's one item that I never had even considered when I first started putting together various levels of emergency bags or "Bug Out Bags," but once I discovered it, I rarely leave home without it!

If you watched our DVD series, Survival Skills, with experts from Sigma3 Survival School, you'll quickly know what I'm talking about as he used it in nearly every scene.  That's right, a Folding Saw.

I cannot stress strongly enough, how important this tool is.  However, more important, is that it's a quality folding saw.  I had the chance to work with a few different saws and was shocked to see the difference in quality.  

Check out this short video, and leave your thoughts below.  What item is your most important?
