Screwdriver:
- body= used triplanar for the main shape and then added the fluting by sub-masking.
- ball end= I made a circle mask at the very end, inverted the mask and pushed in the circular butt end using the gizmo tool. Then added a sphere and scaled and placed it at the back end.
- shaft= cylinder, non-uniformed scale it with gizmo. Selection masked that end of the shaft, inverted, non-uniform scale in the x direction, used trim and projection to shape the flat-head end.
