I thought "Duck" was in reference to the Yellowhorse Duck buckle and bolo. Wow, try saying that 3 times fast!!
The knives fall into 2 basic groups. The first and biggest group describe "samples" from our special projects department. They span many years and there are a
lot of knives. Right now these knives occupy two large mobil racks and the racks are parked in my office.

I sell one knife and it does not impact the crowding condition I now find myself in. I need to sell the entire contents of one box to make a diference...but then there are over 25 boxes! I may never see my office floor again.
The other group is made up of knives from the company archives. These are duplicates. My directive was to go through the archives and if we had two of something, the extra one should be sold. It does not matter how cool the knife is either. For instance, I found 2 proto type 184 sheaths! I almost fell over when I saw them! They are identical so one must go.
It just did not make sense for Buck to have all these knives packed away in boxes where no one could see and enjoy them.
We are using Ebay because it costs us each time we add/subtract a knife from the web site specials page.
I hope this helps answer some questions.
