Very interesting reading Steve, thanks for the snapshot
Frank, I know it works, they use Cryno on racing cage and bike parts, makes all the difference in the world, it is not cheap, but at those levels it is worth it, and if it did not work the race teams would drop it like a hot stone.
Is it worth the extra money for the average turner?
Well, I can only speak for myself, and I'd say no, but for a pro who spends all day in front of a lathe, extending the working time on a tool from say 5 minutes to 20 or 30 minutes, yeah, I could see that being worth the extra cost, as the tool would last longer, and you would up your production by turning more and sharpening less.
