Making railings out of 2x6 stock, 122 in long. The center will be

the corner where the sloping top face meets the remaining (about 3/4
in.) vertical edge. Other than sand paper. Think homemade threshold
where the slight top slope meets the edge. Thank you!

Grind a scraper profile using an old saw blade (either handsaw blade
or circular saw blade) and scrape the profile? Possibly, form/grind a
profiled blade (iron) that fits into a hand plane?

Man, I hate people who cut up old handsaws instead of using
them as handsaws.

Anyway, a slight roundover like the OP is talking about is
a job for a block plane. It's just 3 or 4 strokes, and will
go very quickly even on a 10' plank (it didn't take me long
to take a 12', square stock to completely round, when I made
the mast for my little dinghy).
