Gday Marines.
After a lot of searching for knots to match the hudson and Drake Paracord necklace. I came to a dead end. Well life is a funny sometimes. While on a job site the Electrician was tying his extension leads in a funny manner so it wouldn't twist the inner wires. When he was done, I asked to look at it and bingo here it is. The simplest knot you could ever do. The hardest part is getting all the loops even. here is a pic of the screen used necklace
Here is a pic of the knot that i believe that was used in the film.
Would love to hear what you think. If this is the correct knot. If so ill get a you tube link up soon.
