I highly doubt this will happen on this run. History shows that when GEC does a run of knives, they all (including SFO's) have the same blade shape. The only differences being nail nicks vs. long pulls and satin vs. mirror finish. The Navy knife IS the short run of this group. Of course, I could always be proven wrong.
Personally, I'd love to see another run of 15's with a single spear long pull..... I just pray they put end caps on it!
My dream 15 is actually a single one arm Northfield, with end caps, snakewood covers and a bail. Not exactly the most popular blade shape, but since we're dreaming...

. Heck, I'd settle for a spear long pull in this configuration. I keep scratching my head, wondering why no one has commissioned a Northfield 15 yet.... the rope knife doesn't count!
