I beg to differ, and think this is a misunderstanding of how product refinement works.
That’s usually a tedious and grinding process of continuous adaptation, making a lot of small changes in conjunction, rather than bold blowouts. And it’s a dance, often, with every two steps forward requiring one step sideways or back.
This is true of Apple (I happen to know a bit about that), even though in public presentation the attention is drawn towards the spectacular. The "breakthrough communication device" Jobs put center stage back then was the result of such a sysiphean task. Current macOS (and, hence, iOs and TV OS etc) are the result of slowly grinding away at it for 30+ years at least - I’d even say 50+ year, including its Unix and MACH roots.
And I believe it to be true in general. If a given blade has exceptional qualities in some aspects, improvement may do well to take that design into account and build on it. Yes, seemingly minor tweaks in handle shape, ply thickness, gluing process, material selection, tooling optimization, blade balance may be exactly this: the continouos grind at product improvement.
It may also be callous marketing, certainly. But don’t make the mistake that improvement, creativity, are like divine flahes of radical new insights. It is not. Everything is hard-fought and tedious.
