Best guess I can come up with is a PVC gutter and a pair of shears?

Plexiglass?

I think that would be too brittle (in thin enough sheets to make
cutting easy).

I offered "credit cards" as an idea as that's about the "sturdiness"
that I need. Yet, cutting a credit card (e.g., in half when it
expires) is relatively easy.

Cutting with scissors/shears is easier (and more versatile) than
with a "saw"
