A few of you are probably aware that we sell mil-spec kevlar parachute cord. It's a hollow braid cord made from untreated kevlar fibers. Naturally it's very strong, as we would all suspect since Kevlar is used in some types of body armor. It's the sort of thing that you find out about and think, "Neat, I'd like to try that out." However, I don't feel like it's suitable for many bushcraft or survival applications. Here's why: 1) UV light causes kevlar to degrade. This is untreated, uncoated kevlar, so it has zero protection from sunlight/UV rays. With constant exposure to sunlight, kevlar will lose 50% of its strength within a few months. That's not ideal for a cord you undoubtedly bought for its strength and plan to use outdoors. 2) I've heard two instances of it breaking in winches. It's a natural thing to think of using kevlar cord in a winch, but that's not what this cord is designed for. With no protective sheathing or treatment, it seems to cut into itself, fraying quickly. One customer lost a pretty expensive crab pot that way. 3) Yesterday I used it for a project here at the house. We needed to pull two fenceposts together, so I used a trucker's hitch in Type 9. It worked great, but afterword I could see a lot of fuzzing around the friction points. Similar to above, it was abrading itself. The question is: how much strength did it lose due to that abrasion? And we'll never know the answer because I chucked it. Kevlar parachute cord is ideal for rocket parachutes and it seems like people like it for kites. I would probably stop selling it, since it doesn't line up exactly with our core business. However, we now have a few corporate and commercial customers who are buying it for its intended purpose, and I hate to give that up.
