I was wondering what techniques and/or tool everyone uses for cutting the foam core boards? I tried using a small toothed saw, a serrated knife, and my exacto knife. All of those methods left me with a mess of foam bits everywhere and uneven bumpy edges. The exacto knife worked best, but still not great. Any suggestions would be greatly appreciated icon_smile.gif Thanks!

I get mine cut at work, but I have read on many forums that people use a tool called a hot knife foam cutter. If you google it, there are all different kinds and prices. These knives cut foam with smooth edges.

I use an exacto knife and use a SPS plate to keep the edges straight. Good luck, cutting those sucks.

Exacto knife or a box cutter. The box cutter has a wider blade so to me it cuts smoother since it goes all the way through.

i've used all sorts of knifes and cutters and by far the easiest way to cut my 1/2 inch foam boards is my steak knife! and i'm talking a cheap steak knife to. keep it upright and push down and up...i never have a rough edge icon_smile.gif HTH

I use my exacto knife..After I draw my outline. I go over it once just to cut the surface. Be careful not to to make the "sawing" motion. Then I go over it again, making sure my blade goes all the way through. It will still make a little bit of a mess, but not as much with the sawing motion. Be sure to replace your blade if it's been used a couple of times.

UpAt2am, is your steak knife serrated or straight?

Ditto thumbs_up.gif . You get a much cleaner cut with one.

I LOOOVE my hot knife! Found one at Michaels in the wooden crafts section for like $20 and used my 40% off coupon. Cuts through 1/2" like it's butter!

I just wanted to add that my Hobby Lobby will cut foam core for you. Some do, some don't.

Thanks mamawrobin, that's good to know I can always go to Hobby Lobby if I need to. I usually go to Michaels since it's closer, but I will definitely keep that in mind!

I actually have an electric knife I'm going to try since several of you have suggested it. If that doesn't work well for me, then I will check out the hot knife at Michaels....love those 40% off coupons. Thanks for the info Kell0006!

What a great site/forum! Anytime I or anyone else needs info or tips, you fellow cc'ers are all right there to help! thumbs_up.gif
