Alpine Butterfly Single, Double Loop and Overhand knot Issue.

[Dennis Pence]

Alan,

I like your new Double Butterfly in Reply 12 and 14.  But playing with it some I decided that I wanted a little more symmetry.  Instead of inserting the bight to the side of the legs of the original loop, I like better to bring the bight down and up in front (which affectively puts it in the middle).

Both yours above and the one I propose below might take a little less rope to make the two loops compared to the traditional Double Butterfly, but they might not be as secure.  It is also easy to insert a ring or small pulley for all of these.

Hi All,
       When you guys start the topic, "Dual-loop Butterfly tying" reminds me it is about time to do something, so offer my friendly tying method. Also, offer what I know about the Butterfly knot and Overhand knot.

       I don't know much about the Dual-loop Butterfly. I learnt some from you guys, and did some research from YouTube.
       There are many variations out there. I like  unique idea from Евгений Романенко.
       See this "https://www.youtube.com/watch?v=2nZO2KVqPU0" and "https://www.youtube.com/watch?v=XujCv90Rt_gand ",
       I combine other ideas, that means, basically, you can drop the loop of a Butterfly knot from the front or the back and also the finishing loop from either the front or back and turn into  Dual-loop Butterfly.
       Anyway, before I came up with my first Dual-loop Butterfly, I tested the popular traditional Dual-loop Butterfly, the jam threshold on the weak side of the eye loop, which is about 400kg.

       My first Dual-loop Butterfly failed and the second one is decent. I just hope someone can test it on the field.

       To Denis, both loops are secure and safe, and I don't deserve to have my name on the loop that you have posted.
                Thanks.

My hand drawn images in Reply #15 do not do justice to the tightened knot.  Further, what is pictured there is similar to the Girth Hitch Double Butterfly.  You can add a half twist before tucking and get something similar to the regular Double Butterfly.  Below are images of what this might look like.

           Two nice looking improvements Butterfly knots here. Both are easy tie and dress.
           Need to test it for sure..
