Thanks!!!! I actually have a few gso's. I have difficulty differentiating between convex and flat when looking at them. What really threw me was a thread that I just read talking about the early S!K knives that were ground by Bark River. Apparently, those knives had a convex grind. Also, I would swear that I read a review that mentions S!K having a convex micro bevel.
On a separate note, it is interesting how the convex edge is touted as being the "toughest" edge geometry, and yet S!K is one of the toughest hard use knives on the market and they use a flat edge and micro bevel.
