Hook
I have uploaded the hook designed using your pictures with an opening mechanism that I imagined it should be contained in the hook handle, I didn't know if the mechanism it is supposed to be for locking purpose or for opening the hook safety hatch so I choose the second version, in which the handle acts as a hook safety opener. The exterior overall dimensions are respected as much as possible knowing that these are more important in judging the design in this contest.
