A heated wire is the best way, there are instructions online to make a basic one with a 9V battery and some wire.

The only other option is to use a VERY sharp long knife, xacto blades get dull fast so make sure you're using a very fresh blade extended out long, any burrs on the knife blade will cause jagged cuts.

I've made a hot wire from a guitar string and a soldering gun. It worked really well actually.

I replaced the heating element (tip) with the guitar string and tensioned it with some screws driven into wood. I've seen this sort of setup used in scenic shops with lengths of 1x to hold the wire out so they could cut into huge styrofoam pieces that were as big as a car.

For a one off, I just use a blow torch to heat up some bailing wire with the ends wrapped around scrap wood pieces. If op doesn't have a blowtorch, they should anyway.

I have 2 blowtorches, but i wouldn't have figured that out.

Do you have any other Maker secrets?

The only other option??? What about a hot knife? Made specially for cutting foam.

>tools that i dont have.

The OP specifically mentioned that they didn't have specialty tools. So I offered the only options that are readily available to them.
