We do have G10 handles on the assisted openers, and we occasionally kick around the idea of putting G10 on others as well. We can't really comment on whether anything like that is actually planned right now, but if you don't mind, we'll take this opportunity to learn more about your thoughts on the idea.
People love the RAT1 because it's inexpensive but not cheap. A knife you can take with you anywhere because you're not afraid of losing it, since replacements are readily available and inexpensive. Any of the design suggestions you're bringing up would raise the price, so where would you guys draw the line? We wouldn't raise the price on something like this more than we had to, but it's always a concern when upgrading a popular design and we'd love to hear your thoughts.
