I've used scary sharp for various purposes
(except flattening plane soles :-) for the last
few years.

It's served me well. Because I'm lazy,
I've simply glued some #400 paper to glass,
and I lay the other grits on this.
This means I can work through a large
range of grits without reglueing,
and I only need a small glass area.

I *know* that I get slight edge dubbing,
but even on paring chisels, it's tolerable.

Side to side edge dubbing when flattening
is not a big issue.

But I always had trouble with card scrapers.

It only recently occurred to me that 1/64" of dubbing
on both sides of a 1/32" sheet of steel might
be "an issue".

So I re-filed the edge of a home-brew "made from a saw"
scraper, and worked it on oil stones (India fine,
followed by slate finishing stone).

OK. Epiphany. Instant wide, curly shavings.

Summary: scary sharp is great, but not for scraper prep.
