I will probably keep one of these Sandvik scrapers./

Iggy, I've only met two people who actually knew how to scrape the ways
on a machine. Both were OLD, and both made their own tools from HSS
blanks.

Although I'm sure the carbide will last longer between replacements than
a hand-honed edge, these guys both "tuned" their tools about every ten
minutes. I think the attention to the "instantaneous" condition of the
edge made a big difference in how their work turned out.

My question with a carbide scraper would be, "How do you tell when it's
not quite keen enough to do the quality job I want?" And then, of
course, how fast can I get new inserts?

I learned rather quickly that indexable inserts get dull, too! G

Lloyd, I can guarantee 100% that I will never scrape any machine ways
that are worn, as a restoration project. I will keep this scraper for
some minor jobs, like repairing dings.

They're great for scraping off 30 years of glurp from your cast-iron fry
pans. Ask the man who owns some. d8-)
