Andy,
1) I understand #1. Actually - I have been torn on the bullseye - and would like to leave that one up to you. Move it as you see fit. I would like it toward the rear of the blade - if you can find a good spot for it - and even drop a pin - that is fine by me.
2) The slant of the handle toward the ricossa is to get the thumb to the blade in the chest lever - but also in the reverse cut (where you put your thumb on the blade and cut toward yourself). I have been using, and frankly modifying, other knives of mine to have this feature. I think, with the dimensions on the handle, it will be right.
I have had three knives with the cup you speak of and I find taking it off makes the knife more usable.
3) The swell at the butt (the one Tony and I are calling the Asswell) is like Ray's Bushcrafters I think:
In fact, I drew - studied multiple knives - redrew and redrew what I thought would be right - and I ended up with what essentially looks like a damned Woodlore from the top.
Not my intention - but I think it is right.
I reserve the right to be wrong - and can always send it back, hat in hand, and have you take it off!
Thanks for being cool and making what I ask, even though I may be wrong.
