I think this is how these are - the thing on top of the blade is the spine and it doesn't extend over the shank.
It's role is to create the correct bevel angle when honing.
I included the picture from a razor with a spine, that's indeed how they are, that's not the picture of my razor
It's a little misleading, I meant that mine is missing that top piece, my bad!
