straightedge & utility knife. Cheap, works all the time!
In that case i use 12" metal shear with piece of styrene on top so magnet would slide easy.
Pretty muchTrying to picture this, its a thin piece of styrene under the magnet sheet to keep from sticking to the base and you just slice away?
We have one of those but has a metal surface. May try laying some scrap cardboard under it and see if that helps thingsmaybe a guillotine cutter?
Ditto on the guillotine cutter, I use it all the time for mag cards

We have cut hundreds (Probably Thousands) of sheets of magnetic with rotary trimmers. The rotatrims are great, but there are other brands too.
I agree that it can be scored, then snapped clean, but that is one small extra step. If we can cut all the way through with one motion, that saves time.
I have cut many sheets by hand too, but I try to avoid that if I can anymore.
