loneeagle, welcome to the Yard.
as others have said, one knife is up at a time.
Right now the Muk is king, but previously the SOD was king.
We don't know what will be king next, but I for one am looking
forward to that.
Others have mentioned the secondary market exchange on Bladeforums.
Also checkout the Bussekin Exchange which is run by one of our own senior
forum members.
Look at the sticky post put up by ColdOne, that steelfan was talking about for
information on how to find them.

Cheers
