I learned a lot of the knots and hitches I use from this site. One of my favorites is the Beer Knot (https://www.animatedknots.com/beer-knot) which I use to make little loops out of paracord. They are one of the few things on the site that are not exactly a hitch or knot but an object that makes tying other knots easier. In my bike repair kit I carry a few in different diameters.

If you wrap it around a pipe or tube using a cow hitch or prusik, it creates an eyelet that is as reliable as if it were welded in place, but is also easily moved by loosening it slightly. On bicycle tours I use them to create ad hoc eyelets on my racks which make lashing oddly-shaped things on the rack easier. They also work great for converting a small diameter eyelet into a larger one.

When you tie your shoe laces, you're probably using a square knot [1] but with double slip. If your shoe laces often open while walking, you might be doing it wrong (granny or thief knot).

If you want to learn just one new, very convenient knot, which can be used in many situations, I recommend the Bowline [2].

As kind of a knot guy, unlike other commenters this is my #1 favorite knot site.

Other sites with animated 3D models might be useful for visualizing the topology of knots, or something. But for actually tying the knots I find this site and its curated photos much more practically useful. The fact that it's not literally animated is a feature; it shows the key stages you go through, rather than every detail.

And the photos are just clearer and better than any other resource. (If you look closely you'll see a lot of editing work has been done on them like to minimize the diff between consecutive photos.)

Only downside is that I wish it had more minor knots!

To anyone into knots, I recommend Knots 3D on Android. It is really handy because most people keeps the phone with them all the time. Beautiful and well maintained app. It's not overwhelming, in the sense that it doesn't try to add every existing knot in the same database, it has usage, which gives context, history and specially related knots, which makes it possible to compare different related knots that are usually used for the same thing.

I've got the Android app and love it, as well as Knots 3D.

Most knot enthusiasts will already know about it, but in the analog world The Ashley Book of Knots is fantastic. Beautifully illustrated; the author, Clifford Ashley, was a marine painter and spent decades documenting almost 4,000 knots.

How are more people not obsessed with knots?

It's the purest form of human creativity! It's nothing but a strait line and humans have figured out how to twist and turn it into a million different objects and endless uses. Our entire species has propelled itself into a realm of knowledge built on the fundamental twisting of a simple lines and observing those properties.

The clothes you wear are knots. Every surgery you have ends in knots. The combined effect of knots on our technology and understanding of the world is fascinating.

Only humans can see a rope, have a picture in their heads of what it should look like and then set forth on creating it. It's just such a precious nugget of what it means to be human and have the urge to fuck around with shit.

For those that want to nerd out old school:

> The Ashley Book of Knots is an encyclopedia of knots written and illustrated by the American sailor and artist Clifford W. Ashley. First published in 1944, it was the culmination of over 11 years of work. The book contains 3,857 numbered entries and approximately 7,000 illustrations.[1] The entries include knot instructions, uses, and some histories, categorized by type or function. It remains one of the most important and comprehensive books on knots.

There is some duplication/variations in that count, e.g.:

I know similar web about paper airplanes (maybe I found in HN too some years ago):

Love this site. Bought their app a couple of years ago and started learning knots by tying them over and over on repeat during zoom meetings with a couple of lengths of paracord. Slowly building up a decent collection of knots!

I particularly like the comparison between similar knots that helps you understand when one is better than the other.

Super useful website.

Knots seem like boring and obscure useless knowledge from a time long gone, but since gaining an interest in them as a result of getting into bushcrafting, I'm shocked at how often knots come in handy even in day-to-day life. When I was a boy scout, and I was doing my knot merit badge, they did not put any effort into demonstrating the use cases of the knots they taught us. If they had, I'd have been hooked then. Took over a decade before I revisited it and realized how cool knots are.

A skill I will definitely be teaching my boys in a more practical way when the time comes.

A chill little puzzle game where you swap hexagons to untie a knot:

When I was in my late teens and early twenties, I worked offshore for Santa Fe International on a pipe laying barge. There, I learned the applications and strength of 3/4 inch rope. As a "rigger I", I've tied off almost anything on the deck during almost any kind of storm. As a joke, I once tied off an anchor, attached to a buoyed, two inch steel cable. The deck foreman was not amused.

Is this a very high quality website that simply tries to do one thing well and isn’t trying to monetize?!

I know it’s foolish but I want to daydream for a bit that the Web turned out differently. That at some point around Space Jam the people decided that a business being online was a deeply offensive invasion of Our space and would be boycotted, so they gave up on trying. And what was left was lots and lots of webpages like this among the personal pages and pages about nothing. And that services like search engines were provided by universities. And undergrads who attended would take their turn working for these services as a sort of community service rite of passage.

We have web rings and web rungs (more of a ladder topology) and nothing was for sale but the community would be fine with the occasional grandson selling meemaw’s knit scarfs. Oh, and Zombo Com was tolerated given its sheer breadth of utility.

I want to stay up well past my bedtime some summer night, finding some new web zone filled with a clever collection of someone’s identity they shared with the world. Maybe while a breeze gently wanders in through an open window and a train ventures forth in the distance.

It seems to be a nice, handmade, thoughtful collection. Things like being able to flip the images is a nice touch.

However, name "animated" will only lead to disappointment for people finding slide shows of humans. This is basically the same kind of that a Boy Scout handbook provides.

There are three things that I usually do when I’m anxious, waiting for something, and not at my desk: (i) Read a Book, (ii) Play Chess, or (iii) Re-watch the Knots 3D on the Phone.

This website was so useful for Boy Scout rank advancement.

Reading this thread as a furry is...interesting.

Interesting site. The layout and interaction flow feel well thought out, and the minimal design makes it surprisingly refreshing to use.

I loved knots, lashings, plaits, braids, and splices as a kid, this really brought me back.

also this has been discussed on HN before: https://news.ycombinator.com/from?site=animatedknots.com

I love the idea of this site but have always been disappointed by the fact that it's more of a slideshow than actual animations. You have to do a fair bit of interpolation if you aren't experienced.

And, for reference, one of the historical encyclopedias of knots is the ABOK.

https://archive.org/details/TheAshleyBookOfKnots

What's missing from linear serialization of a book format like ABOK and this website is metadata tags that indicate each knot's attribute(s), i.e., bight, open, slip, etc. and an ability to browse and filter by such tag(s).

I wish I did scouting as a kid. Knot tying seems so fun and useful.
