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?"

Ah, if you're like me, you'll know right away. I can barely push the darned
thing when it gets dull.

All but one of mine are made out of old files. The one that isn't is a
Nicholson, which looks exactly like one of their files with no teeth, but
with a flared tip. That one has a thigh brace for pushing it.

And then, of
course, how fast can I get new inserts?

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