I agree, I absolutely love flippers!! I thought that I would like the 0560 so much better than the 0550 for this reason, but I actually like them equally. The deployment of the 0550 feels almost like that of my 0350. I've been carrying the 0550 more than the 0560 lately, because it fits exactly where I want it in my pocket.

As far as losing pocket knives, I think the way you carry it and the design of the pocket clip are very important. Since I live in Boston, I carry my folders concealed in the pocket in the same direction as it would be if I was using the pocket clip.
