Joseph Gwinn fired this volley in
:

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

I don't know what the alloy is, they only state which inserts are
recommended for their blades. But yes, it does feel like 1018 or such.
Files easily, but has good toughness; mills like a dream if you limit feed
depth.
