Bifold knob location

I have three-panel (as opposed to louvered, two-panel, six panel, etc.) bifolds and need to know the best knob mounting. Issue #1 is knob placement. Issue #2 is terminology.

The knob might look strange mounted in the center of the panel, as opposed to being mounted along the door edge next to the hinge. Your opinion?

Also since they lead to walk-in closets they would be less likely to catch clothing if they were mounted on the door that does not face the opening when the door is opened.

I've seen a decent answer at http://www.stretcher.com/stories/05/05may02e.cfm but I don't understand the terminology: He talks in terms of a leading and following door. Which is which?

My Johnson hardware refers to a guide and a pivot door. I think the pivot door is the one closer to the jamb when opened, and the guide is the one facing the opening when opened. Correct?

 

Think of the safety aspect. If the knob is near the hinged edge, there is danger of pinching your hand when closing the door.

 

The leading door is the one that slides, and the following door is the one with the pivots. There are discussions as to where the ideal place is to put the knobs, but convenience and safety are the important factors. I have found customers like the knobs in the middle rail on the leading door, just to the inside of the leading stile. It allows you to open it with the knob and close it as well. Whereas locating it in another location doesn't make the opening so smooth. Try this, grab the middle rail in several locations to see where it opens best for you, and put the knob there.
