I use these all the time. I offer one as an option when someone orders one of my larger blades. In my opinion, the Combat Master is the best nylon sheath available right now.
Have you figured out how to do a high ride carry with it? Fold the belt attachments over and lash them down through the side eyelits with the paracord. Use the loop formed for a belt attachment. Great if you get in/out of a vehicle alot. Also, the thermo plastic insert is removeable, which means if its too tight or too loose you can take it out and adjust it. Use a heat gun to form it to your knife. I wrap my blades in two layers of masking tape to give a little clearance.
