Paracord looks simple but not simple as it looks. Its quality differs a lot in terms of different materials and weaving technics. Before diving into this field, we bought varieties of samples from Japan, the States and Europe, including those local well-known brands and hot-sales on Amazon and eBay. The test turns to be surprising and disappointing. We discover that over 50% of the samples are inferior made with polypropilene and polyester but vigorously propagate they’re well made of nylon. This is the reason why we set up the brand “Amba Cord”, only selling genuine nylon paracord. But this is far from enough. We furthermore creat a brand new weaving technics to make the shield with better abrasion resistance than traditional shield. And this would be easy to tell if you have a Amba Cord paracord taking in your hand.
