I have looked around the internet trying to find out if someone else makes these like I do.  All I can ever find is a monkey fist attached to a cobra weave, or the same with just an extra length of cord.  I hope that this helps someone, and that it is as enjoyable to make as it is for me.  

Supplies needed:

1. 1 3/4 inch steel ball ( I used an old mouse ball with the rubber cut off of it.) you can use a larger one, but you'll have to augment the length of cord needed.
2. About 20 feet of 550 paracord cut into 2 10-foot lengths (better to have too much as not enough.)
3. 1 D-ring, or similar item of your choice.
4. 1 shackle and a key-ring.

Tools: 
1. A pair of forceps, or a scribe ( looks kind of like a small icepick.)

Start with a monkey fist knot,   
but make sure you do four raps for each side, and instead of only having a short length of cord on one end you want an even couple of feet on both ends when its done.
You will need this to make the handle. Once you have your monkey fist made you'll need to thread the other length under the two middle strands between the ends where the cord comes out of the monkey fist, and pull it through where it is even in length on both sides.
Then you use the cord lengths to make a "Round-Crown Sinnet," which is just a crown (box knot) with a twist....
