Have you ever wondered what a knot looks like rotated 40° or maybe 90°? Or maybe you want to see what a Trilene knot or Constrictor knot looks like from the back? Use your finger to spin the knot and see how it looks from any angle in 3D!
Choose from 101 different knots and see how they’re tied in incredible detail. Watch the knot draw itself and pause the animation to see where the virtual rope goes in and out and around. (Something about a rabbit and a hole and a tree right? ) Zoom in on the knot to get a closer look or flip it around for another perspective. Can your old school knot app do that?!
Each 3D knot has detailed information including tying pointers, strength and reliability, structural info, and Ashley reference numbers (ABoK) and occasionally the history behind the knot. Knots are listed with their common synonyms or localized equivalents. Localized for over dozen languages including: English, Arabic, Chinese, Danish, Dutch, French, German, Hebrew, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish and Turkish!
The knots are arranged by both Category (Boating, Climbing, Fishing, Scouting, etc) and Type (Bend, Loop, Stopper, etc). If you find a knot you like or want to come back to later, add it to your Favorites list for quick reference.
