I always remember, back in the day, when Norm Abram had to turn a set of legs or similar on the American program 'The New Yankee Workshop'.
He'd badly shape one, with seemingly little knowledge of how to use the tools, leaving a really cut up finish. Sand it into something that looked really great (yeah, right), then use a copy lathe that left an awful finish for the next 3 whatever's and seemingly sand them to match the first.
As far as I can see (I stand to be corrected) all Carbide tools are basically scrapers. Yes you can get a good finish off a scraper, if you know how it works and use it properly, but beginners pushing scrapers into lumps of rotating wood seems dangerous to me. Almost back to the old school days of scrapers made from old files to make a bowl for Mum!
