Hello All,
I just received my Filarmonica Corte Cabello razor. It has some sort of black rubber around the tang of the blade which unfortunately has stained the scales black.

What I'm wondering, and don't tease me for being silly, is whether I'm supposed to remove the rubber? I assume I am but I just want to be sure.

My second question is what purpose does such a rubber piece serve?

Thanks,
Stultsy
