IMO, a pocket clip on the SAK Soldier would be awesome! Case did it, why not Victorinox or Wegner? To me, ease of carry is more important than one handed opening. Some of the SAK's are pretty heavy and clip carry could definately be an advantage. And as far as the metal ring attachments are concerned, I just attach a Reeve style lanyard so that I have the extra paracord with me.
