Step 5: Tying the knot.
I used a reef knot / square knot to secure the wrap onto the handle.
I then take a rather blunt homemade needle and jab it into the end of the cord to poke it through the hole in the handle. The melted end keeps the needle from punching through the cord. I have found by sending the ends of the knot through a hole like this further secures the knot. Also in this case keeps the wrap from wanting to slide down and off the end of the handle.
