All About Pocket Knives

I have some very interesting trading material (old, new, rare) availble in my search to expand my Whittler Collection. Just give me an idea of what you're looking for if you have whittlers you'd like to trade (pattern, brands, handle materials, etc.) Thanks!

Edit: I've had some very satisified takers over on the Case Collector's Club Forum. Age and condition are more important than if it's a splitback or not.
