How to Cut Foam Board
Cutting Foam Board Insulation
Foam is lightweight, fairly cheap to buy, and has a multitude of uses: packaging materials, house insulation, foam sculptures... and lots of fun uses.. just ask model railroaders, table-top wargamers, or diorama makers!
I use foam for a rather boring purpose. I buy large sheets of styrofoam board and cut it up to protect items I ship. Sometimes this means reinforcing box walls, or just protecting fragile items.

The Best Hot Wire Cutter for Foam - Ideal for craft projects, architects, and for any other job that requires PRECISION
This hotwire cutter looks like the best deal. It has all positive reviews and even customer pictures of their final foam sculpture!
I haven't tried this one, but I thought that I would first recommend the tool that seems to be best for making exact, measured cuts. (Something I haven't been able to do with a box cutter or hot knife.)
Utility Knife (Box Cutter) does the job, but causes a bit of a mess! - (Not recommended for precision.)
This type of construction knife does a good job because the blade can slide out as long as you need it. It you cut the foam slowly, at an angle, you might manage to do it with minimal mess.... but I usually end up with the floor covered with white dots, AND the edge of what I cut is ragged :(
A Hot Knife is Another Tool for Cutting Foam - Not for making small cuts, but great for big projects.
I've used this one, but the "knife" is much thicker than a wire, so it doesn't make small cuts in the foam. This knife would probably work best for cutting large pieces of foam, or for making holes or cavities in it. Check out the below video, which does a good job of showing how it works.
I wouldn't recommend this one for jobs that require precise cuts.
The main advantage over using a utility knife is that you don't get all of the tiny foam pieces breaking off and going all over. The disadvantage is that the melted foam smells, and so you'll need ventilation.
