Here is a few shots of the Mods I made to the sheath
I borrowed from the genius of Paul Scheiter and ran some elastic shock cord through the retention straps of the factory sheath. It has been over a year, and the straps still spring open-well out of the way of the egde, and make drawing the knife VERY easy (I found that "out of the box" the straps would curl, and snag the choil like area of the knife). The proceedure was simple. I just punched a pair of holes near each of the snaps, and criss-crossed the cord around the swivel, pulled snugly, tied, and fused the knot. This also had the extra benefit of still alowing the straps to spin, but gave some added friction, so they don't spin so easily.
Here you can see the position the straps spring and hold open to when unsnapped.
