Good Day. I went to the antique store with my wife and found a couple of single edge razors for $3 and a little elbow grease. One was a GEM Junior (brass looks like). The other was a "Auto-Strop" in a metal case. We cleaned/oiled them but my question is kind of a silly one, how do I load them/what type blades do they use? The GEM it looks like you just push the button on back of the head and set a SE in lining it up with the notches, trouble is the blade won't stay still, I've looked at these online and best I can tell mine isn't missing any components. The auto-strop I'm lost on completely. Everything I see there involves actually stropping the blade??? I want to use these bad boys but can't figure them out Any help would be greatly appreciated. And I apologize if this is a "time-waster" of a question. Hope everyone has a great day/night!
