I'm pretty lost with the number of different formats for single edge blades. I bought a Above the Tie aluminum single edge razor a while back, SE1, along with some Kai Pink and also some Feather Super Pro blades, both 'Artist Club' style blades. I've also bought a used 'Lady Schick' razor that holds 'injector' style blades. I've also bought a vintage GEM that holds 'gem' style blades. Anyways, I've read that Schick Prolines were a good choice of AC blade in my ATT SE1. I ordered the pictured box of Proline's and waited a month for them to get to Canada on the slow boat from England. They don't fit my SE1. So, although there is no key on the box of blades to load my injector Schick, I was able to push a blade into the Lady Schick. It fits, but it doesn't shave. I lathered up, tried first pass, and thought this is either the mildest shave ever, or its not shaving at all. Rinse off. It was the latter. So two questions: what razor holds these Schick blades, and how do I ide
ntify the Schick Prolines that would fit my AC style SE1? If I can figure out what to order I'll wait another month for them to arrive and try again.
