the only secret to making a thin band strong is to make it tall
Whatever is their secret in the design or manufacturing process, the look does not suit me, as I have short chubby fingers and do not like the look of a tied up joint of roast beef, if you know what I mean.

what did you end up requesting from DK for your setting?
Make it tall and tapered. Almost all of my Kataoka rings are made this way. The height of the shank is 2mm, and the width is 1mm that tapers to a milgrain knife edge.
I haven’t had any issues with them, and the longest I’ve had one of their rings is six years. Once I add them to my rotation, I wear them daily for weeks or months.

I love your collection of Kataoka jewelry and really enjoy the thread you started. I have often wondered how comfortable these pieces are to wear.
I think their claim of having a "secret" is freaking nonsense. I just think they aren't stable, period. I think some designer pieces like Kataoka (as @JPie said), have actual ways of making thin rings sturdy, but it means having them be taller, tapering, etc. The rings that OP posted seem to do none of that, so I suspect they will eventually warp and/or break.
Heat treatable allloy? Its expensive and a real pain to work with but its one possibility if its not hot air.
Its been around since the 70s in one form or another but never caught on.Interesting.....never heard of this before!
In general yes somewhat stronger..Would handforged band make it stronger? I have a very thin maybe 1.2mm band handforged 18k gold. I didn’t ask the jeweler to make it that thin but he did, I wonder if I will have issues?
Almost all jewellery is cast these days. If the band was made by hand forging it can be tougher.
But how ever it is made the main strength issue is the bottom inside the hand where it takes a beating.
This can be hammered after assembly whether cast or forged.
gold alloys work harden and soften with successive heating for soldering.
Would be curious to hear/read real customer reviews after a year or two of daily wear- as to how the rings stood up to wear & tear. (And not to the pampering mentioned above).
