USAKnifemaker.com has several styles of replacement, low ride pocket clips available. These fit the standard "three screw" pocket clip used on many knife--many Benchmade and Emerson knives, for example--and replace the standard pocket clip with a titanium clip design to ride lower in the pocket. I find a lower ride to be more comfortable and also obviously more concealable.
I have a few en route to try out and will post up more details when I have 'em in-hand. However, I thought I would pass these along as a tip of the day, for any of you struggling along with bad pocket clips!
