I think that you have a winning design with the folders ! The flow is excellent !
But. . . . .
Without seeing a spine view of the top two. . . .the scales and bolsters look boxy/bulky. The knives are very streamlined and have a slim appearence. You would probably get rid of that boxy/bulky look if you softened the edges, dramatically.
With such a streamlined appearence and the visual effects of the damascus and beautiful wood, the buttonhead screws complicate the flow and make the knives visually choppy. I think that they are too big, plain and don't follow the beautiful arching pattern of your knife.
I hope that you don't mind, but I took liberty of taking the top picture and performed some manipulations to get rid of three screws. The pic is attached. To secure the bolster and scales, I think that you could use a beveled flathead screw and attach from the liner-side. If not, recess all of the screws and use a smaller screwhead (stay away from a buttonhead - except for the pivot). Something like the screws on the carbon fiber folder.
Again, stunning designs ! Definitely winnners !
