Beautiful things have a price tag… and here there’s a lot of work behind a process like this (not putting it in a saucepan with acid and then in water and bicarbonate and giving it a little electricity)… Even Damascus steel costs a lot of money even though today’s industrial production processes are enormously different from the artisanal ones of decades ago…

At least you know that yo-yo wasn’t cobbled together with nothing except leftover grain boundaries.

This leads me to believe the process was as follows:
- Bar stock of crystallized Ti was received.
- Bar stock was machined into desired yoyo shape.
- Yoyo was etched to reveal grains
From a manufacturing perspective, I think this makes the most sense as it minimizes dimenstionality (vibe) issues from a post-machining heat-teat.
