The question in my design philosophy would be the amount of purchase that you have to control the blade at a particular length. In some of my designs like the Lil' Temperance and the Caribbean designs, I do bring the handle to the edge without a kick ( like the basic Endura family ) or a a finger choil. But they are not lock-backs. I would have to modify the Starling design quite a bit to serve your request. It's possible. I have a new design coming out soon called the "Rock Jumper" that is a lock-back that brings the handle to the edge. I'll watch reaction to that new design.
Lock-backs have the strongest self close and some of our customers find that as a high value.
I'll watch for other comments.
