Thanks - pardon my ignorance, but what is meant by "set"?

Set is the deviation of the tooth from the plane of the sawblade.
A sawblade that just has a simple ^^^^^ sort of profile cut out of the
blade will cut a slot of exactly the sawblades width.
If you push each alternate tooth up and down out of the page, then you
get a wider cut, which means that the back of the sawblade has a wider
slot to run in, and does not bind as easily.
This is usually a good thing.
