I think it is looking better and better! Great job for an early design and more importantly you are listening to feedback. I see good things in the future. You came to the right place for feedback too, nice!
I'm personally not a fan of jimping but that isn't really important, what is is that it is nice and comfortable. I like to make sure they are very smooth and well finished before heat treat. Jimping is a trade off, you are less likely to slip up on the knife, it aids in some control... on the other hand it won't be as comfortable over long term use.
The grind could be great, saber grinds are well proven and a great choice for a camp knife.
The handle looks fine to me, keep that drop to it for sure.
aesthetics of the triangles... I tried some in earlier designs and looking back I don't like them, to each their own. I see where you are coming from though.
One thing to consider is that with a saber grind you probably want some weight behind it for light chopping or at least nothing to catch when splitting or plowing through material.
Keep up the good work!
