Hey that's a pretty cool razor. I like it. But what I have always thought of as a frameback is a seperately forged spineless blade held permanently in a pressed steel spine and tang unit. I know, others use the term differently, but to be technical about it, I think @bouschie gets the cigar. Still you have a very unique razor with an intriguing design. Could you post a pic of the screws or blade holding mechanism?

The classic frameback was born out of economy, I believe. Less cutlery grade steel was needed. Less skilled forging and grinding. I could be wrong but I bet they were cheaper to manufacture, in their day.

So your razor... how does it hone, and shave? Can you get a replacement blade?
