I've snapped two pruning saws when the blades got seized in branches on
the
push stroke.

Were they 'good' ones? (Silky etc)

I think one of them was a cheap one,


I would expect a cheap one to blunt quickly and bend rather than snap
as they generally use a lower grade steel.


The ones I have had from Lidl and other places have been made from
hardened carbon steel


Maybe that's still cheap to source in India / China. ;-)

which stay sharp but can crack if abused. They cut
on the push and pull stroke but it is best to put most force into the
pull, to reduce bending.


Check.

I've had well-used ones break (perhaps from fatigue cracks) before they
have lost their sharpness significantly.


Maybe they have gone the other way then, making them too hard or
hardening them throughout, rather than case hardening them?
