The styroport cutter
The watts? What kind of cutter?
I'm talking about the cutter for cutting styrofoam, tempex, polystyrene, styrofoam or better known as styropor. That white, lightweight synthetic craft material, available in all kinds of shapes .
Of course, you can cut it with a knife. I sometimes do it with small eggs or balls or on the back of a shape. If it's okay if the cutting edge looks frayed. Then a knife is fine. Cutting with a knife does give clutter, small static balls fall off. But if you want to share it neatly, with a nice, straight and tight line or cut off a piece, then there's... the styroport cutter !
And... a nice fact: you can also cut foam rubber plate with it!
