I too once lost a knife in pretty much the same way, and ever since I've had a dislike of pocket clips.
I carry my EDC Strider/Buck Tanto in the SOE pouch, which has worked fine thus far. However, I carried the knife for quite a while before I got the pouch and removed the clip so I could comfortably carry it in the pocket of my jeans and cancel out the risk of losing it.
Since the Strider folders are significanlty bulkier than the Strider/Bucks, I doubt you'd ever be able to lose it if you keep it in your pocket. I know my Strider/Buck is bulky enough for me to hang upside down or what-have-you without it ever falling out. Or, better yet, get one of those fine SOE pouches.
