550 FireCord has come a long way since I last wrote about it. Live Fire Gear smashed their crowd funding goals for the project and it is now entering the final stages of production. You can expect it to be available sometime in October.
The product itself has been refined considerably. The 550 FireCord prototypes shown during the crowdfunding effort was basically just para-cord style nylon sheathing around a thick tinder strand. The more refined version will actually have regular nylon inner strands like standard para-cord with the addition of a color coded tinder strand. This should make it more durable and useful as survival cordage.
550 FireCord will be available soon at Live Fire Gear.
