It has an intriguing name and is not widely known, but it is useful and easy to tie. It belongs to the large family of “loops, eyelets, or nooses on a single rope,” at least according to the definition in the “bible” of Clifford W. Ashley, The Complete Book of Knots.
So, if you need, for example, to set up a block and tackle to reduce the load in tension, if you need to secure a package, or simply create a hitch point on your rope, here’s the weaver’s knot: it’s tied in no time, and unlike knots generally used by less experienced sailors, it can be undone even after enduring very strong tensions.
The temptation is to make a simple loop with a simple knot or a figure-eight knot (as shown in the photo above), but keep a good knife handy if you want to untie them after heavy and prolonged tension. Let’s see how to tie the weaver’s knot. First, create a nice long loop at the desired point along the rope.
The second step involves rotating the loop onto itself.
At this point, you need to “fold” the figure-eight that has formed (downward in the photo).
Now comes the key moment for executing the weaver’s knot: first, locate the central passage created at the center of the figure-eight.
Then, pass the end of the loop through it, from underneath.
Now pull (upward in the photo), always keeping a bit of tension on both ends of the rope.
Finally, after tightening well, the weaver’s knot is complete.
