Here are some of the development process I used to create the final shape. There were also a lot of 3d model revs and prints to get it to were it is now. I am also including some close up pictures from a sample on my desk so you can see the texture and curve of the handle. The initial idea came from an obscure reference that I came across about creating products for delicate surgeries and that it is best to try to have the fingers closet to center access of spin.
