Yes, folks will collect anything. Where did you find them? The Norelco I used in the 1960s was a two head shaver where the top popped open to brush out the cuttings. The shaver was made of two plastic parts the lower one was gray and the top part was white.
One of the ones I won is similar to that, except it has an off switch.
My grandpa shaved with something similar to that, he had been using it for decades until he died. As far as I know that's all he ever used.
