Tom, the TI in the faux tortoise came from the vendor with a curved spine and straight edge. I'm sure the edge was that way from the factory since the vendor is not a a razor/shaving specialist and the edge was far from shave ready. I also beleive the spine and edge should be the same. If one smiles the other should too.

Harold, Glad to se you back. I'm happy to hear Tom got your razor dialed in. I find I'm leaning toward vintage razors also.
