I wanted to know if anyone has any insight into the Due South knives. Did they just buy some GEC's and mod them or are they like a Northwoods, made by GEC to their specs? I have one, a #15 that was a ball and chain that has the hole filled in, plus a modded spear blade. Are they collectable or just a good candidate for a user. Mine is new with the box, pin, patch, etc
