They really can't be made any thinner unless you want them completely flat. Any thinner and you wouldn't be able to counterbore the screws and pivot far enough to be flush and the pivot would bottom out before clamping down on the scales. Anyway, they're thinner than the stock grips, this is how they're staying. I have a lot of different color G10s and micartas coming up in this style. I have a carbon fiber version with an inlay planned, but I'm still shopping around for CF I really like for that. There's really no plans to change the style of this knife though, I'll just be moving on to other knives.
