They are like cutting 130 year old Doug fir
They cut at a good rate and are light easy to handle. The over length adds a good shove and some quick clean up cuts to the handling.
The sawdust turns to powder so not much makes it out the dust shoot. A damp rainy day will keep the dust settled but when the sun comes out the dust drifts.
Back shaving takes out the set and wears the sides off the teeth. However it works for cleaning off the patina and keeping the size, saw marks are a plus on this job.
It dose take a lot to grind that and the nail strikes out so I have been using 6-8 of my older saws per day and I buy half of them.
They had a batch of 9 1/2 x 9 1/2 they wanted 8x8 out of. Those cut fast, saved a paneling piece off all sides, next.
