The waistband carry certainly seems to protect better from scratches, but its not as much fun as pocket carry because you can't fondle the knife without drawing it, and because its so much out of the way that you forget you're wearing it and forgo the associated pleasure. My problem with pocket carry is a possibly nutty fear of losing the knife by catching it on something, or just having it work its way out of the pocket. Reeve explicitly warns in his instruction sheet that the latter is possible, and I've found that if I forget it for a couple of hours, it does work its way up as much as an inch. So here's what I've come up with.
I take a 36-inch length of thin black cord, and fold it in half. I put the folded end through the loop in the leather lanyard near the point where it passes through the lanyard hole. Then I put the two ends of the cord back through the folded end so it forms a loop around the loop in the lanyard. Then I bring the two loose ends together and tie a fat knot in them (a figure eight knot works well). I put this end up under my belt and tuck it into my pants. To get loose, the cord has to pull out from between your body and your waistband; make a right angle turn; and then again pull out from between your belt and your waistband. This radically reduces the possibility that the knife can fall out of your pocket unnoticed. You can test this by pulling it out and letting it drop. On the other hand, a firm yank on the knife will pull it loose easily. Also, you don't have to untie any knots to get rid of the cord when you want to--you just pass the end of the cord back through the loop you created. Admittedly, all this is not as elegant as unencumbered carry, but it sure adds to my peace of mind.
Incidentally, this gimmick is not entirely original. Something similar was described on another forum and attributed it to one "Ken Cox."
