NB - The Barnett "strike-nine" and "Black Widow" slingshots have steel forks that do not pass through the entire grip section - as I discovered when I disassembled my old "Black Widow" slingshot a few years ago. Not a very convincing setup from that point of view.

Saunders products for this type of design are superior in every respect.
