This is the spine on my brand new Ti Evide Sonnant 5/8, which was honed by a very reputable honemeister.
Both sides of the spine are flat. One side more so than the other. This is reflected in the bevel being different to either side of the blade. (It seems to go further up the blade on one side)
I'm wondering is this normal trait on a new Ti from the factory?
If it wasn't brand new I would have thought it had significant hone wear.
Here's the pics.
