I would think shaping with heat. I never like to have a bend in the handle bend to much. It’s usually the last place I get working. Seems like if it was shaped with set it would already be bending to much.

Just my 2cent worth. But I was always thinking that the deflexed handle was t make a shorter bow with a longer draw. The reflex to give so early string tension. That’s just my guess though.

 You're looking at it backwards.  It's a  double curve/gullwing.

I guess I’m still looking at it wrong. All I see is a deflexed handle and relaxed mid limbs.

Wouldn’t a gull wing have a reflexed handle then deflexed inners and reflexed outers? I’m not seeing that in the picture I’m looking at.

Maybe I’m thinking that the belly is the back?

Sorry about that. Seems like a design that you might try to salvage a bow that took to much set already.

Add the deflex unless it is natural. When I build a bendy handle bow I like to feel the handle bend only as I hit full draw so the handle area remains stiffer until late in the draw.
Exactly. Evergreen advice. 👍🏽

 The design was nearly universal over a very large area for quite a while.  People still puzzle over exactly why but it would likely become clear if we lived  in that era and area.

  Even with sinew the same shape was often  used.

Thanks Pat. I know I probably should but I have never studied artifacts.

It does seem like a very odd design. I’m wondering how it does shoot? It seems like they got it bass ackwards. Especially for sinew backed. Very interesting

Isn't it just a bend through the handle reflex deflex design?

I guess not. I thought so to, but it’s reflexed in the handle and deflexed through the mid limbs. Exactly the opposite of what I was thinking.

Now you guys are confusing me. In the illustration in OP the back of the bow is to the right?

Apparently I had it backwards as well.
