I have an Old Timer like this one ( belongs to Sergent666, borrowed the pic from the SAK thread as to not derail it ) and another with only the clip blade. Mine are really worn though, the clip blades both have huge recurves in them. I only really recognize them because of the clip blade. The only difference between this one and the other I have is the other has a little liner-lock and only has the clip-blade instead of the clip-blade and the penblade.
Anyway, I've just been wondering what kind of knives these were for a while and this is the first I've found a picture of them to demonstrate. I don't really have a great camera so I haven't wanted to take pictures of mine.
