I just performed a little "tweak" to my EDC knife. And I hope Sal Glasser (of Spyderco) doesn't see this!
I cut the molded-in plastic pocket clip off of my Dragonfly with a hacksaw and ground it flush with the side of the scales on my grinder. This makes the knife 50% thinner, and since I keep it on a keychain I have never once used the clip.
Then I got a couple of large ball bearing swivels (the ones used for fishing) and added on to my knife and my light. This way both can rotate freely on the 'biner I use for a keychain. This lets them lay "flatter" in my pocket but also makes it a lot easier to use both implements.
I'll take a pic when I have a chance.
