So far I've searched on Amazon and eBay, but have found very little
*small* sheets. Nearly all such sheet material comes in large sizes. I
only need a piece approximately 50mm square.

I even thought of buying a length of white Contiboard and sawing with
a hacksaw just under the surface so as to separate the plastic from
the chipboard. Another idea would be to immerse a piece in water for
24 hours, which should soften the chipboard considerably, perhaps only
needing a craft knife to separate the plastic from the chipboard.

I had about a dozen pieces of such surface coverings, each with a
different pattern and about 2"x3" with a hole punched in the corner and
held together with a small chain.

Samples from a kitchen unit supplier, like this...

Or type "Formica sample" into ebay...

Incidentally, 'Formica' was originally developed as a replacement for mica.

I don't quite follow - what properties does it need? Is this about
flatness/rigidity, or about resistance to tools?

It has to be flat and it has to resist wear from a tenon saw or
Japanese pull saw. And my kitchen worktop has withstood 16 years of
wear and tear (albeit not with saws!) and is barely marked. So I
reckoned that that's the material to use. Just the thin hard plastic
coating.

Ah. Formica, worktops, plastics, FR3-ish, none will offer any significant resistance to sawblade wear. Spring steel does.

Maybe, but if I attach the "face protector" slip using e.g. spray
mount, I could replace it with a new piece when it gets scuffed.

As you said. Why not be sensible and glue something on that'll last a while?
