Tying a soft shackle

[Tom]

This is the best tutorial I have found on tying a button knot for a soft shackle. Its from some high liners so the diameter of the dyeema is less than required for winching. They discuss not only the knot but a number of ways to tighten it. They also test each for strength. Enjoy.
