Thanks, that's very interesting...
so maybe single-bevels and open sheaths went hand in-hand... but a single bevel does not necessarily mean an open sheath (Talibon?) but an open sheath makes for a single-bevel to be ideal?

Would there be any good way to figure out if it was diffusion, isolated innovation or a mix of both?
