The fork scoop is about 53 wide and there is a transition to the handle that is 9mm wide. Exactly at that transition the fork was cut in a longitudinal section and the profile is shown in this figure. The thickness is 1mm and the curvatures of the scoop and handle are in different directions, 3mm depth concave in the handle and 10 mm depth convex in the scoop.
