Hit on this idea while feeding pets and I already did a search on this and found a lot of mixed answers.
Please nicely correct anything I get RAW wrong in this question.
First off; False Focus lets you totally ignore any material item or requirements for them up to 100Gp assuming your focus costs at least that much.
That means, as I understand it, if some spell required a stack of 100 gold coins or a 100 go pile of diamond dust or any other component, you can ignore it.
A practical example would be Create Armaments. It should be able to make any weapon for free, up to 100 go of value, out of nothing since the material component was an equal value of diamond dust. Basically substituting energy from the focus for the matter.
I'm about 95% sure I have that part correct.
Now the messy part of the question; Fabricate.
My understanding of the spell is it turns a stack of raw materials into something else of equal material value to those base raw materials.
An example would be some wood and iron into a sword.
How does false focus work with that?
Can I take, for example, a generic 1 pound, 1 sp hunk of iron of sufficient mass and volume and use falsefocus to ignore 100 gp value requirement? To make a....say Superior Lock from that iron ingot. That's a 50 gp item to craft.
Edit: For that matter, do I even need the chuck of iron?
Some sort of consist answer would be nice. An official answer would be awesome.
