When I first got into making Evo loops I got to the point that I could tie the button knot without a 'cheat sheet' but after a few weeks my muscle memory faded and I couldn't tie one now if my life depended on it. But what's cool about the button knot is that the tails are tucked inside and no raggedy ends are flailing in the breeze.
W/ his version of the Fast Shackle the ends are back sliced before the knot is made so that there are no fraying ends and the part of the shackle that gets knotted is thicker.
