Would I buy these personally? No but IMO from above it's better than many.
It's a sub 6mm head, most of us here play that range or bigger. Players CB's for reference are in the 5.5 zone your KZG blades are for sure much thinner.
In regards to the taper on the toe It's not common but also not so rare. In fact the ONOFF Forged has that feature as well, It does have a purpose.
The broken in 3 parts I don't get it. The pic you linked us to is at a very different angle, looks like a muscle back as well.
I would classify it as a thin top line, low offset, and Japanese neck style and it looks pretty good.
Keep in mind I have a fixed ranged zoom lens which makes the head look much bigger than it actually is.
Here is another image for you ( again zoomed way in )
