Proxxoning a Chinese Copy?

I made one with a diamond abrasive saw of the type jewellers use to cut rubies and emeralds, for cutting the hard stuff like carbide.

ebay - unfortunately they aren't on sale any more.

Thinking about a chop saw too, with a serrated slitting saw blade - but again that would be for metal, not wood.

I've been thinking of making, or adapting, something to cut PCB material, which is copper faced fibre glass.

Can you offer any advice, please?

At the moment I use a handsaw and this is very much a vague maybe nice to have.

In descending order of goodieness:

Laser.

Waterjet.

Shear or guillotine. Or, if it's thin enough, strong scissors.

Score and snap.

Bandsaw. Eats blades though.

If you must use a slitting saw, you will need carbide - HSS will blunt in no time, as the laminate is very abrasive.

As the laminate is only about 1-2 mm think, finding a saw which obeys the three-teeth rule will be almost impossible.

Another possibility is a thin metal cutting disk for an angle grinder. Put it in an arbor in a mill, or in a fast table/chop saw, and you can get it to do accurate cuts. You don't need the power of an angle grinder to cut laminate.

forgot to mention, a diamond lapidary saw blade also works, but is slow.

Or the speed, 1000 rpm will do. And a 1mm ULTRA THIN METAL CUTTING DISC (the ones meant for stainless work well) doesn't eat your fingers nearly as easily as a toothed blade.
