Purpose of Ceramic/Gummy Stones

[gwat]

Some people do; TYROLIT, the Austrian grinding wheel manufacturer that makes grinding wheels for ski tuning machines, makes a range of elastic files that they market as an alternative to diamond stones https://www.tyrolitlife.com/en/produkt/elastic-files/

Gummy stones are elastic bonded abrasive blocks; they are made from elastomeric resins to which abrasive has been added. They vary in hardness from Shore 30A to Shore 95D. Elastic-bonded abrasives are widely used for grinding and polishing operations in many industries. The "ceramic disks" that Wintersteiger uses for edge grinding are actually elastic grinding wheels https://www.tyrolit.co.uk/divisions/metal-industries/industries/sports-industry.html

Does anyone have experience with these? The Sidecut videos make it seem like the Tyrolit ceramic and Elastik stone set can fully replace diamond stones?
