Cutting Foam Board

I went ahead and made a prototype of my chariot racing game by printing out the circus, trimming the paper on foam board, using spray adhesive, sticking the paper, and laminating it using a laminating pouch pack.

Everything seemed fine, except for one thing, it was a devil of a job cutting that darn foam board! Scissors hardly dented the darn thing. I used a sharp hobby knife and that did not seem to do much good.

I ended up using some sharp kitchen knives, but it left the board with a not too nice edge to it.

There must be an easier way to cut the thing. Does anyone have any suggestions?

X-Acto Knives?

I've had success using an Xacto knife and a straight edge (a metal ruler or something) to score the foamboard, then bend it along the score line and it pretty much snaps apart.

More accurately I fold it the 'easy' way to sort of complete the score, then fold it back the other way to snap it apart.

Note also that this method makes for a good fold-line n a board. Just skip the 'snap apart' portion and make sure you measure well so the fold-line is in the right place (or it folds off center and that's a little janky).

Utility Knife

We use a utility knife with a metal straight edge (t-square).

Cuts through the board in one pass.

Sharp X-Acto knives work pretty well for me. Other things I'll note are that it helps to have a really long metal straight-edge. Obviously, a straight edge helps guide the cut and make it smoother. The longer it is, the less times you'll have to reposition it, reducing the number of variations in the line. Also, X-Acto makes a little plastic knife (that uses regular X-acto blades) that has a guide on it. You can set the guide at 90 or 45 degrees. It helps ensure that the cut is vertical or angled. I find this pretty useful for making polished cuts in foam board, though it does take slightly longer than just whipping through with a regular X-Acto or utility knife.

there are actual specific foam core knives that you can buy. Sort of like Matte knives for picture framing, but with set depths for foam core. Some of them can set bevelled edges.

Anyway, the illustration made me literally LOL. and yeah, a nice sharp Xacto/OLFA utility blade and a t-square/metal ruler will do the trick/
