- This version of a Stronger Soft Shackle MK 2 will create a shackle that is 230% stronger that the breaking strain of the rope. This is our new favourite soft shackle as it use a simple overhand knot to create the stopper knot, making it much easier to tie than other variations which use the Button Knot to complete the shackle.
If you need to get the gear to help you complete the splices you can get it by following the links below.

Once you have tied a couple of these you can complete them in minutes, all you need to do is two Brummel Locking splices and one overhand knot. Making this version of the soft shackle by far the easiest that I have tied.
The only down side of this version of the stronger soft shackle is it uses slightly more rope, you have to ensure the tails of the brummel splice with are tucked into the main part of the shackle are long enough for it to extend past the knot and into the main part of the shackle. This gives you 4 thickness at the key part of the shackle (just past he end of the overhand knot). These four thicknesses of rope is what give the stronger soft shackle the breaking strain that is 230% greater than and individual length of rope.
The team at bottom up boats hope you enjoyed today's video and that like us this is not your favourite soft shackle. We believe the MK 2 is far simpler to tie making it a winner in our book.

This is a much nicer and simpler version than the standard one I see in use for climbing. Thank you for this. This video deserves more views.
Thanks for stopping by and for the feedback. Glad you liked it 👍
Very nicely done...cheers!
Thanks for stopping by and glad you liked it.
The key to the strength, as I analyze things, is that you have four thicknesses going through the closing loop, as with the button knot. However, I had a hard time getting the bury to extend past the knot, which was huge, even after I tried hardening the knot. I made one bury about 8 inches and it is there. The overhand knot is much simpler, that is true. If I have the time and patience, I prefer the button knot which is smaller and takes far less line.
Yep, the four thicknesses is the key to the +200% breaking strain. A big knot helps which creates the issue you called out, after a few you figure out how to get the lengths right. Thanks for stopping by and taking the time to engage.
Looks like a great way to make a soft shackle. I followed along with the video using 1/4" (6.35 mm) line, 39" (1 m) long and when I got to the part where the overhand knot is tied, I found that my line was too short to tie the knot. I'll try it again using 48" (1.2 m) and see how big of a shackle that yields.
It is a great way to make them playing with the length you will quickly find a formula that works for you. Thanks for stopping by and sharing how you got on.
additional note: At the last minute, I decided to use 60" (2.36 m) of line instead of 48". That turned out to be too short again. I ended up with a knot the size of a golf ball and a shackle about the same size. It takes all of the loop to open it up to slip over the knot, leaving no room for passing the shackle through or around anything. Probably at least 84" (3.3 m) would result in a useable shackle. Of course, a soft shackle using 1/4" dyneema is way overkill for any of my applications.
