Thanks Mark , appreciate your help.
Guess I’ll be investing in a heavier duty modelling knife , the ones I primarily use are the standard ‘exacto’ and scalpel blade types , which can be difficult on your wrist/hands when applying pressure on thicker styrene , repeatedly.
I’ve tried the sanding paper method also, but in this case (for my particular MF hold parts) I had placed them - when they’d all been cut - into a tabletop mini vice and sanded to shape using beauty nail files !

The beauty nail file can work as well, especially when the styrene is thin. However I recommend sandpaper, something between 400 and 800 strength, just try it.
Regarding the knife it should be definitely a heavier one. The blades can be changed easily and if they are fresh they are sharp enough to cut also smaller parts.
Cheers
