Can one burnish a hook on a TC blade with a harder material (say a diamond coated rod) and use it like a card scraper?
I tried a steel scraper from two cherries (0.6 mm) and one from Arno ( French Spring Steel Super Hard 1 mm) and a hss plane blade. Flattened the sides and edge (back and bevel for plane blade) and burnished a hook with a carbide rod. Got shavings but the hook doesn't last on the steel scrapers. Hss is decent but I thought why not try TC. Can someone explain why it will/won't work - there's a post where someone claims that it worked. After all if the geometry is the same and material is harder, it should work.

And here's a TC scraper:
