There is another string going about saw sets.

I don't remember who told about it. You put the saw in a vise and simply place a flat blade screwdriver between the first two teeth and twist.
This sets one tooth to one side and the other to the opposite side. Then you skip to the next two teeth and repeat. You do this until all of the
teeth are set. I have done this and it works. I also have about five saw sets including an antique Taintor set.

Google "Taintor saw set".
