Awesome. The internet is amazing. Always there is a definitive site for any particular topic and this is the one for knots.
I am a newbie and a casual student of knots. I don't have hobbies or work that requires me to tie, so I don't put the knots I know to practical use that often. Certainly there is a knot for every purpose which brings me to my question.
I want to tie a knot at the end of a strap. What I am working with is a automotive tow strap. It is about 2 inches across, made of woven .... poly ? Originally it had a metal hook on the end - the strap fed through the circular attachment point of the hook and stitched back, flat on itself. The strap didn't become un-stitched but broke just behind the stitching. I don't know of anyone that has a sewing machine that could re-stitch the strap, so I would like to tie the hook back onto the strap.
I realize that from a safe use aspect I should throw the strap away and buy a new one. The strap was rated for towing an automobile - I guessing a 5,000 lbs rating. I would not be using it for automobiles but I think it could be used for light duty work. Say pulling a snowmobile or ATV.
I have tied straps together before using a simple overhand knot on both ends. One strap receives an OH knot and the other end ( second knot ) traces the path of the knot by coming in from the free end. It is a permanent knot and cannot be untied but it is quite workable.
My thinking is to use that knot to attach the hook. I am wondering from which direction I should bring the free end into the knot. I have taken three pictures to illustrate what I mean. The strap in the pictures is not the tow strap. It is a rubber strapping about 1/2 inch wide and a small keyring to simulate the hook.
The first picture just shows the knot in its correct usage to join a strap together.

The second is one way of tying the hook in. The strap gets an OH knot, the free end is fed through hook and then the free end comes back along the loaded line of the strap. Another way to describe it is that the strap is fed through the hook and doubled back on itself and an OH knot is tied in the doubled strap.

The third picture is an alternative that may be either stronger or weaker than the knot in picture # 2. It's simply the same two knots but with the free end fed through in parallel but starting from the standing end of the strap.

Pardon my misuse of terminology. I'm not sure I am using free / standing end for the correct parts of the strap. As far as I know the joining of two ropes / straps would correctly be called a bend. The abomination that I am proposing could perhaps be fairly called a tangle. Of course, if it works, it could be called a useful tangle.
Thanks for your input.
