    Ever make a Kamikaze knot? 😲
    If so, I hope you never have to use/test it.

    I am sorry, but I found this a really bad video. He is saying that the decorative knots have practical uses, but doesn’t explain. He is doing it just way to fast and meanwhile the camera view is changing. He was way to enthousiastic about the sandals. Fun to watch, but no one is gonna make it. I would rather have the more practical knots like for scouting or sailing or climbing. That would be a lot more practical.

      The practical ones are there. There are some examples with the decorative ones.

    Good gravy… why do you cut away and switch camera angles when he’s trying to show stuff. This isn’t the time to be artsy with the editing. I need continuity to follow what he’s doing. Maybe it’s just me…

    • Jinxy Katte

      December 23, 2022 at 10:14 pm

      Its not you. It totally ruins it for make and makes it impossible to follow.

    December 23, 2022 at 9:29 pm

    I’d love to learn how to tie these knots, I thought so many condensed into a single video would be amazing… then I struggled more and more, because the camera angle changed so much and it feels like there were just way too many cuts during the actual tying of the knots. Just look at the prosperity knot. I could only follow that with lots and lots of rewinding and slowing down. Sure this isn’t supposed to be a tutorial, but man, I think the tying of knots is equally as important as the functionality when talking about knots

    • Kristen Kakos

      December 23, 2022 at 9:54 pm

      These look more like demos, which makes sense for the show.

      JD has a YouTube page – Tying It All Together – he has tutorial videos there that are single camera angle.

      It took me years to learn all these knots in Sea Cadets, granted now I can do them blindfolded underwater in a sinking ship, but hey!

  11. maxim menage

    December 23, 2022 at 9:55 pm

    It would help if there were zero cuts when hes executing the knot. It completely messes with my focus.

  13. Jinxy Katte

    December 23, 2022 at 10:13 pm

    As soon as you make a cut and change the camera angle it becomes very difficult to actually follow along as you lose all sense of orientation…

    Here’s how to get knots without tying anything, handfree.
    1. Put an untangled wired headphone in your pocket. Let it sit in for one hour, effect escalates with longer time.
    2. Take it out. Voila~

  29. wbfaulk

    December 24, 2022 at 3:23 am

    Most of these are more just knitting with rope than practical knots. Obviously, knitting is just a series of knots, but I think when most people think of knots, they’re looking for how to fasten things together, not how to make decorative mats.

    I’ve seen some comments about speed and camera angle here. Love what Wired has done – it is more of a demo than a tutorial. For anyone interested in learning more, JD has a (huge!) collection of single camera angle tutorial videos on his YouTube channel: Tying it all Together. He also has step-by-step books.

    When greatest human inventions are mentioned, the wheel, nails, the compass, the printing press etc. come to mind, but ropes and knots should be at the top of that list. Because of its practicality and versatility it is still a very important and irreplaceable invention.

    The double coin knot is really easy to remember. Working clockwise, make the the right-hand bight in your left hand. Over (first bight), over, over to build the top bight. Then under, under, under to build the left bight.

    I’m interested that he chose iterative structures as the more advanced levels, rather than going for some of the more intricate knots like a bottle sling or a monkey’s fist. I was happy to see the zeppelin bend, though

    About 6 or 7 years ago my son was a Boy Scout and I was an Assistant Scoutmaster. I came across J.D.’s books, and bought one of them. Every week I would craft a different neckerchief slide to wear. I still have about 20 of them. A lot of them I gave out to boys who didn’t have a slide. It was a lot of fun making them. If you’re reading this, thanks J.D.!

    He misses a great opportunity to define his terms – every knot is a combination of loop (line crosses over) and bight (line does not cross). A bowline is a loop on a bight.

    There’s nothing worse than a bunch of cuts in a turorial video. It creates discontinuity and makes the demonstration extremely difficult to follow, especially when fine motor skills are required. There should be no cuts at all during the demonstration of each knot.

      youre not alone. im no experienced knot tier but i know how to do a few of em. and as far as i understand, it really takes being able to visualize the knot in your mind to be able to understand the mechanics of it in real time. it isnt impossible though, like they say practice makes perfect!

      not saying that for certain though, just my opinion~

    Interesting selection of knots. I was surprised that you chose the single fisherman’s over the double, or the zeppelin bend over the sheet bend (on that point, I was under the impression that zeppelin is better for ropes of the same size… the sheet bend is for different sizes). I also half expected a sheepshank to be in here somewhere, but I can see why it wasn’t.
    Thanks for the video!

    Y’all are really posting a video about knot-tying and in the middle of a knot, cutting away to the person’s face, then not having the knot be the same as before the cut happened.. lol. actually, you make a cut every few seconds. awful.

    What genius decided it would be a good idea to change camera angles multiple times in the middle of each knot being tied? Idiot, really

    Knowing Wired magazine’s reputation before they sold out to Apple and Google adware, I’m just gonna ignore these videos before they get any more racist and sexist.

      And by the ten second mark, they’ve already shown ya how to tie a noose. Hey, if anybody remembers how to find the F8 key to access BIOS before your OS boots there’s some more racist sh*t U.S. programmers put down there too!

    The instructions are good and clear, however the video editing not so great.
    I would appreciate if the video editors could keep the video focus on the knots tying, and not cutting it back and forth between different angles.
