Anyway, I would make a fixture out of a
hardwood like Oak (for the damping) with metal clamps of some kind,
and use an ordinary HSS cutter.


The wood jig is a good idea for its vibration damping characteristics.
Total rigidity isn't a really big deal, since finish isn't terribly
important; just angle and balance. One thing they state as important as
that there be no "camber" in the angle. It needs to be flat. Apparently
(from other searches I've done) mower manufacturers work quite hard to
optimize their blade edges for angle and lift.

I wonder how critical it really is, so long as both ends of the blade are the
same, so the blade remains aerodynamically and kinetically balanced.


But the HSS isn't the recommended MOSN PVD inserts recommended for this
particular alloy. And I have them already...

Which alloy is that? I expect that the Honda blades are 1018 or the like,
judging from the feel while filing.

But I'm sure your inserts will work just fine.
