Thank you for an answer in you usual competent style. It constantly
surprises me that although most of us have pursued this hobby for a long,
long time there are still questions to be asked on what, at first sight, may
seem quite simple matters.

I think a further advantage of oblique grain, that I did not think to
mention before, is that it resists the tendency of the blade to acquire
additional, unwanted, undercamber. Following from this it does look as if
the classes that use thicker material for the blades do not usually run the
grain obliquely.
