I've posted a couple of my "Stanaback" style sheaths here before. For this 5" Randall Combat Companion the sheath body was just a bit too small for the EZELap to go on the front of the sheath, so I made up a rod holder that's an integral part of the welt. I've seen bushcraft sheath with fire-starters mounted this way, and all of them created a noticeable bulk on the welt. This method blends the holder right into the body of the sheath.
