that's not how cutting platicard works

you score the line a few times depending on thickness and you bend it until it snaps, non straight cuts are harder buy doable by chunks in the same manner, for smaller random shapes you can use a jeweler style saw

also abs is not 'polystyrene' and might not break as cleanly, that product description is lying to you, i'm pretty sure abs is cheaper and that's why they sell a lot of sheets of that for hobbying now and try to gaslight you

however if you want the thickness to make slabs or something like that look for 'foamed pvc' sheets, those are soft enough to be cut A LOT more easily and you can imprint textures on it by just pressing on it or scraping to make wood grain, picrel is mostly that
