This is a simplified method to make the knot which secures the Wild Edge steps to the tree. For me it really speeds up the time it takes to attach the steps. The final knot has exactly the same wraps as the traditional but using this approach eliminated the need to feed and pull the tag end of the rope thru the loops. I have the 8 foot ropes on my steps and found that in course of pulling the rope thru it often twisted and I would need to stop and straighten it out before pulling the knot tight. This seems to eliminate that twist.
This especially helps for installing the steps above your head if you're using the Wild Edge aider or the climbing method @Cain posted previously. Since the step is over your head pulling the loop down and thru is easy.
In fact I have to give credit to Cain for the inspiration for this when he demonstrated his knot untie method. I decided if you could untie by removing a single loop you should be able to tie in the reverse process. That's what this method does.
Hope this helps.
