look at a pull blade. The teeth are withing the width of the metal.
The rip has a tiny set. A cross cut you have a tool that puts set and
it is a strong set. You press the handle together and a tongue presses
in to a slot of the anvil. This is a setting tool. Every other tooth,
then rotate the saw and align and press the other teeth. The trick is
to get the proper tooth in the proper bent position and all at the same
amount or the job is jerky. Many saws are flopped down on a bench and
the set starts to get out of align. If you don't sharpen and set your
own tools you will never know.

The problem is set is set or set isn't set. One has to measure with a
finer instrument to measure the set in a rip. The set is very tiny so
it doesn't tear the side grain and keeps a cleaner cut.

The crosscut does that cuts back and forth ripping and tearing and
shearing. It is fighting fiber strands on every tooth. The strands
grip the sides of the blade. One wants a wide kerf for an easy cut.

We used to set saws before a job. We sawed many a sheet of plywood to
make book cases long before fancy power tools came to the home owner.

John look at a tooth. Rip is full width and is all there.
A crosscut is angle cut to make and half of the metal is gone.

The shape and use of the tooth is completely different.

Martin, nobody in this thread has disputed that the shape
of rip teeth and crosscut teeth are different.

What you are insisting, which is wrong, and which everyone
has been trying to politely correct you, is that rip teeth
have no set. That is simply wrong. Rip teeth have set.
Hacksaw teeth have set. Pretty much every tooth on every
saw has set(*).

(* the exceptions are when the tooth is wider than the blade,
as is the case with most power saw blades; or things like
felling saws where the raker teeth are not set).
