I hadn't seen that patent.
It's nice to know that Turner blades are still available too.

It appears to me that the issue of lift for catching went down
two paths - one building lift into the bladeholder; another
building lift into the blades. The combo blade clearly won out
with Turner.

I think the fatter fluted Turner blade (Fan Type) came in with the
Turner 'V' base - the first of the Big names to introduce a high-arch.

Gadge, I guess the fatter blades replaced the earlier, thinner flutes?

That's not a blade. This is a blade!
