The one thing that wasn’t discussed by anyone was the “Hang Angle”, the angle of the grip relevant to the saw plate. These plates are roughly 3½” deep at both the toe and heel, so they aren’t really textbook dovetail saws. The original handles have a hang angle of 38°, which I found a little awkward when cutting dovetails on a hunk of wood held in my portable vise as it raises the work level by 6” or so above bench level. I think that dropping the angle to 30° will make the saws more comfortable to work with at the higher position. If any of you disagree with that, please let me know.
So here is the “beefier” final design - maybe...
