Since the new FRN versions will be lightweight you could bring back the Boyd dent and shave off a few more grams from the weight.
Just a thought. I have the current G-10 P4 and I love it. It's probably my absolute favorite Spyderco I've ever had, but I can imagine slightly preferring the boyd dent on it.
Really great job on this design Sal! I can't wait to get my hands on 1 or more of the FRN versions, probably the ZDP-189 and K390 versions you had said were likely to be coming. It has been fun to learn more about your thoughts behind the model and K390 on this forum.
Like Vivi had said earlier, I'd vote for some of the K390 blades to be coated black with the DLC or TiCN? (I prefer DLC) I'd prefer that over a non-coated blade on K390.
Any update on these being released?? Could it be before 2019?
