I actually discovered this by accident and I've never seen anything like it before. I started by applying a final coat of homemade Fixin' Wax to the handle to protect the wood that is about to be covered by 550 paracord. From there I started off like you would with a normal axe wrap but left a little extra excess on the ends just to give me more to work with if something goes wrong and so that I could tuck a little extra under the top and bottom of the wrap so it would be easier to take off and put back on if the need ever comes. Once I got the tag end through the tension loop at the bottom, instead of immediately pulling the tag at the top to finalize it, I wrapped the top tag around the highest wrap and the bottom tag around the lowest wrap one time. I tightened each of those to make sure that I was happy with everything before pulling the tension loop up under the rest of the wrap. When I was ready to proceed, I had to loosen the top and bottom loop enough to provide the necessary slack at the bottom so that enough of the bottom tag could be pulled up through the inside of the wrap and so that I had enough excess to grip with my Leatherman pliers at the top to pull on. Once I pulled the tension loop up inside of the wrap and tightened the excess loops around the top and bottom of the wrap, I was getting ready to cut and melt them. At this point I realized that there was still quite a bit of excess on both tag ends and maybe it could be useful. I decided to tie those top and bottom loops around the top and bottom of the wrap into clove hitches for a better hold. From there, I still had plenty of excess and it occurred to me that the ends could be tied together with a self-tightening knot to make a loop on the side of the wrap. After tying them together, the loop happened to be the perfect size to fit over my knuckles for a really secure grip. This would be perfect for making feather sticks and would probably work well for fleshing a hide as well. My next step was to add a simple lanyard to the lanyard hole. Once I added the lanyard, it occurred to me that a sling could be easily added by attaching it to the lanyard loop at the bottom and the wrap loop at the top. I do not want a lanyard on mine but I demonstrated how it could be done in the final picture if one chooses to do so. Here are some pictures I took throughout the process. Edit: After posting this, I realized it would be much better with the loop on the other side so that I can use it right handed. Instead of redoing the whole thing, I managed to twist the whole wrap around the handle until the loop was on the right side. This also caused the wrap to tighten up more. Update 2/16/19: I have decided to remove the loop from the wrap for safety reasons.
