Absolutely. There was a blanket statement that, "carbide cutters are not meant to be resharpened" and I've heard this before. Without mentioning any particular manufacturer I wanted to say that some carbide cutters can be sharpened.
You point out an important point in this discussion. That is that "carbide turning tool" is a very broad description. You mention the Hunter tools which I have not used. It's plain to see though that these are a far cry from the scraper type configuration of many other carbide tools. So perhaps the OP can get more specific feedback on what he can expect from different carbide configurations.
BTW I think the carbide scrapers are a great way to start as they eliminate the need to learn sharpening and get you going fast.
But I personally want to be able to sharpen my tools when needed so I use HSS. In addition to some larger outfits I have Doug Thompson, Dave Schweitzer and Trent Bosch tools. To each his own
