Going over what has been said.
On both knives, I personally like the finger notch. Very similar to Bob Kasper's design. I haven't had trouble with different grips or transitioning to other grips with this type of handle.
After reading some of the logic here, the thumb ramp on both knives might be a bit much. Possibly a smaller ramp with serrations, or a depression with serrations. Maybe even an even surface with serrations.
On the tanto, I think I would favor a higher grind and narrower edge profile instead of the holes in the blade. As far as the recurve and the "seconady point", I think it depends on how you look at it. To me, I see it as being very similar to an Emerson Commander. Instead of being a secondary point, it looks more like an acute "belly" for lack of a better description. A little more finger guard wouldn't hurt.
The hawkbill a little higher grind line and drop the handle some.
I still wannt them, with or without the changes. Just add the black Micarta or G-10 scales and I'm happy. It looks like you do some excellent work. Good lines and finish.
