The earliest document referencing your knot was by Henry Bushby in 1902 as the Dalliance Knot. Today it is known as the False Butterfly Knot, the Cavers Butterfly or the Half Hitch Butterfly.
I know it as a locked hitch, few of those on a ridgeline provide anchor points for a floating tarp set up, I use them on a paracord line for garden lights too and it allows me to tension the whole rig from one point.
Butterfly knot over here perfect for anchoring mid line... And I learned the knot differently less prone to mistakes... Either way you tie it it's a lifesaving knot!
Yeah, very specific use for rigging. Unfortunately inexperienced folk might use it with tension on the main line without always having a loop load to stabilize that top half-hitch. Could be a problem - requires extra care.
Say you want to lift something using this loop. In this example should you have the rope going out the left side of the screen attached to what you want to lift, or the rope going out the right side of the screen attached to what you want to lift?
@@andrewtorrie8758 Good question, I don't know - haven't seen any testing data or experienced opinion. I've never used this loop knot &, to be honest, don't plan to. As Ben said, it's just a slip knot secured with a half hitch. I prefer to use the Alpine Butterfly or Farmer’s Loop because they create 3 points of secure connection - the loop & both working ends. This “riggers” loop will fail if significant/dynamic load is applied to just the working ends & if the loop is not secured. Perhaps the riggers loop would work well but I choose not to use a knot subject to mis-application. The military uses the farmer’s loop for constructing rope bridges in training. Their solution to possible jamming after very heavy loading is to insert a carabiner in the knot before loading. When done, the carabiner can be easily removed & that creates enough open space in the knot to ease untying. I’m sure the carabiner technique could be used with Alpine Butterfly, too.
Hello Ben, Jose from Puerto Rico here again. Great video. For a person like myself who is not versed with knots, actually I think I'm knot challenged. this was a nice start. Could you as a suggestion, demonstrate the actual practical use of all the knots you will put forward? Like show what knot to use in certain situations with a demonstration? For instance, the reference video you learned this from showed the Chinese fella putting the knot on a hook. I saw that and realized, hey... this is used to maybe lift something heavy. This was very informative on your part Ben!
That's a good idea. You're right by the way. This knot is used to create a rigging sling. As an example, if you are trying to lift an object with a forklift or chain fall, you would tie this knot in the center so that you would have a single point to rig from and the lead line would attach to the object you are trying to lift. It is better than some other fixed loop knots because it can be untied much easier, even after being subjected to loads.
when I was young, I knew this knot, I thought it was the alpine butterfly , but a uncle set me straight. then I forgot how to tie this one. Thanks fir the refresher. lol this knot is not that knot, It's not the same knot? no it's not.
In the video it was said that this is a good knot and possibly better than the Alpine Butterfly. This is wrong. The Alpine Butterfly is preferable to this one in any case. The Alpine Butterfly is very secure and can be untied without any problems even after heavy loads.
Not an Alpine Butterfly, which can be found under different names in ABOK # 532 (and # 1050). Try ABOK # 1038 for what is here referred to as a Riggers Knot. Subtly different knots.
