No, that particular knife was very slim (you were there when I bought it), much slimmer than a wallet and I never noticed it when in my pocket.  That knife is not legal to carry here in Clark County (1/2" too long blade), so I carry a slightly smaller, but definitely more bulky Winchester folder now, also loose in the bottom of the pocket.  I feel it occasionally but it's not intrusive.

 Do you worry about chewing up the sets of your car, or your chairs inside?

Ah, that's a different issue.  My wife and daughter were always worried about that but I told them I had seen no indication of a problem.  Then my wife showed me where the clip had worn the finish off of a kitchen chair.  I no longer carry it clipped to the pocket, but loose inside it. 

Why not clipped to a front pocket?  Simple, my big hands make it difficult to go into a front pocket to retrieve anything else when the knife is clipped into the corner of the pocket.

By the way, you should post some warning when we are about to see man-cheeks.

I think that anyone seeing that photo and registering "Wow, man cheeks" is seriously in need of professional help, Mark!
