550 cord = Duct tape's non sticky equal I bought a roll of this stuff and it is great to have around. I will even go as far as saying that I use it far more than the silver tape. I purchased a roll to work on my knotting skills and have found it useful in many occasions. Today I tied up my fake christmas tree with 11 feet of the stuff cut in 5' and 6' lengths. I used the inner cords wrapped around the branches and tied them up and used the outer cover to tie the very bottom branches. I learned to do the survival braid with it and I tied one to my wifes keys so she can find them easier in her pockets with gloves on. I can't think of the other things I used it on but it works great. I try to conserve it a little bit because it does seem to be priced like gold around here at the surplus shops. What do you use it for?
