Great news, everyone! We've been a survival gear company for 11 years now, and we've avoided selling Wire Saws until today. But now we have a new supplier that manufactures these in the USA for military aviation survival kits. Their saws use a three strand wire with small barbs that act as teeth. It's the best wire saw we've seen, and we're psyched about adding it to our product line. Bear in mind that this is intended primarily for SERE applications, and other survival/camp applications come second. Stored, the saw weighs less than an ounce and fits in the palm of your hand. It's a great addition to a compact Personal Survival Kit, or PSK Tool Module. $19.99 on our site: https://5col.com/products/wire-saw-flexible-16-in-nsn-6515-00-296-2529
