He no longer carries them, maybe it was a qc problem? Not trying to speak for Jon but it would make sense.
Keep in mind that not every nakiri needs to have a geometry like that. I have knives like that, but my current favorite nakiri is not.
Only the Maboroshi line (western) iirc.
Don't forget Jon carried them at one time as well.
Can I get to this point with the nakiri in hand? Well, I'll see if function can triumph, as is.
