I bought this safety from dollar general, I think it was shavely brand, and I loved it at first. I just recently switched to a safety razor and this is my second one from DG. The first one, with me being new I believe I stripped it. So I bought this one to replace it. Now I'm having the same issue, this new one won't let me twist the butterfly doors open. I can hear a click noise when I try but that's it. I tried soaking it in soapy water over night but only once. Any advice? I can't tell if the top of the razor unscrews or not. What am I doing wrong? I was told to keep it submerged in babyoil between uses but that didn't sound right so I haven't been doing that...
