Shaves amazing too, but it needs some getting used to to the extreme smile.

Read post #22 in that thread also

Very informative bit of reading. I like Mr. Korn's thought process. Does it seem to translate into improved face feel/shave quality as he suspected?

There certainly isn't any concave in the lower portion of the blade, and when I place a straight edge from the spine to the edge in the picture, there only fractions of a mm to the belly. It seems as though it would be very sensitive to any pressure on the hone due to this ridiculously small clearance. I'm wondering if the asymmetry in the belly shape is actually due to prior honing chewing into the belly. I guess I could tape the spine for a little more clearance when honing. Maybe I'm getting in over my head with this one.

Here's another pic from the side if that helps.

That wouldn't happen to be a Rosette Ribbon 80?(guessing from the pics)

That razor has quite a bit of honewear and the toe has been tapered as a result, I wouldn't pay much for it if I were you, in fact, I most likely would pass on it.

Edit:

OP, I paid less for my completely NOS Rosette Ribbon 40(basically the same blade except that it's shorter and full hollow instead of bellied) from another seller.

It sure is sir. I like the lines of the Rosette Ribbons, and have been looking to get a Japanese blade. I appreciate your appraisal, and will keep looking.

I think I know of a razor that you might be interested in.

PM sent.

Check out my post from about two years ago, it shows a W&B razor with the same feature but further up the blade than yours. I actually like it because it seems to give the blade some stiffness so it shaves smooth like a near wedge but the blade is nice and light like a full hollow.

Very, very cool blade! There are so many interesting blades out there. I feel as if I'm just scratching the surface.

I think you are waaaaaay over thinking this. Treat it like a normal razor and hone it! I did that with a Korn American Double Hollow (very similar grind) and it shaves like a champ.

Given the wide flats along the spine it's quite possible that it started as properly made razor and it got there by excessive honing.

You are right, though, most of the time full hollow razors have the belly further from the edge. I think the pictures in the library are from razors without much hone wear, but when I put them I just picked the ones that looked sharpest and not brand new razors (it's fairly difficult to focus on the razor point with handheld point&shoot camera in medium light).
But I have plenty of brand new razors without excessive hone wear from the factory and that geometry in the pictures is representative for the vast majority of razors. There's probably the occasional odd one or mistakes, but the idea behind the double grind is achieving more hollowing so a belly close to the edge doesn't really accomplish that too well.

Also there's the asymmetry left-right i.e. with respect to a vertical plane - that's poor grinding (i.e. poor set up of the grinder with different size wheels on each side) no doubt about it.

The Union Cutlery 4 Points have a rather obvious belly also
