I just stumbled upon the bump fighter razor and quite like it. No irritation period even when I shave against the grain which is a miracle for me. Unfortunately I can't find replacement cartridges being sold. On Amazon, Walmart, etc. I only see the kit that comes with the handle and 2 cartridges sold. Does anyone know of any places selling just the replacement cartridges? If this razor is going extinct, is there any other razor that's basically identical to it?
