is it safe to cut the foam with hot knife?

I wouldn't think that would be safe. I used a double bladed electric carving knife like you'd carve a turkey with. Worked great!

I havent tried that. I cant answer to the safety aspect, but as for the effectiveness, i sure it would work just fine. A sharp razor blade works great.

I don't see any reason why you couldn't. I do know that an electric knife usually works best when cutting foam.

You bet, have been using mine to cut the pink and blue insulation foam. I usually have the heat turned up and it cuts just fine.

The instructions say not to- I'm sure there's a flammability concern.As long as it is not thick, you should still be able to feel the heat/warmth.I don't have a foam top, but I am considering using an extra pad this year since I feel some of the coil bumps now that it is 4 years old. I turn my heater off as I fall asleep since I get TOO hot! :)

We used a box cutter with the same results. It is the way the foam was compressed that causes it to flake slightly when cut. You might find a white tape that can be adhered to the edge for a smoother look.

I don't think so - it is foam and would be ruined by cutting, sanding or any sharp tool.

I suppose it could be. I believe that it would be best to do it with a very sharp knife. I have trimmed foam for a camper seats using a sharp knife

The Tool Cuts 8 Inch laminate Reasonably Well. I Did Not Have Attached Pad, However I Don't Think The Blade Will Have Any Issues Will Cutting The foam.

Okay, I did a test on some foam board. It doesn't work very well at all, it still cuts, but starts the paper on fire and is real slow process..and will most likely deform your blade. With plain foam, it cuts just unbelievably well. So, in my opinion, not good on foam board. Use a sharp razor blade.

No, you will not be able to file or sand this. While a hot wire foam cutter will produce acceptable results, it is still not optimal. If you are looking to shape foam, you will want to purchase Extruded Polystyrene Foam (XPS) vice this type of foam (expanded).

slotted carpet knife blade is thinner than utility blade or probably scissors will work on 2'' foam. Hope this helps

They do make a hot knife for cutting Styrofoam, but I have never used one. You may want to practice of a extra piece to see if it works. I found a link: http://www.ehow.com/how_13447_cut-styrofoam.html

Both previous answers work fine, but another trick is to wet the foam, wring it out, then freeze it. Makes it just hard enough to cut cleanly.

No. In these cases it will shred and make a mess so it's best to cut with a "hot" knife sold at many hobby stores

Not sure because the cover would be larger than the pad but I think the foam would be alright to cut just the cover would be larger. We returned ours because to smell was so strong even after months. It may air out in the summer but we got tired of waiting so we sent it back.

To be completely honest, I'm not sure. I want to say yes because of the heated razor. HOWEVER, I used the heated razor to cut a different type of cord for one of my craft projects and some of the material that the cord was made of is now melted onto my razor part. So quick answer via what I've done is yes you should be able to cut it, but you might ruin the razor in the process. Normally u can scrape the melted stuff off while it's hot but this stuff on mine is still sticking.

I would be cautious of types of foam you try cutting with it.. it's intended for styrofoam. Even Styrofoam needs cut in a ventilated area. I would contact the manufacturer on safety precautions on cutting foam if your referring to the spray can type or the home insulation type as it could release deadly cancerous gases that could kill you. If your referring to the spongey foam used for sponges or for stuffed in packing and corners to pack around a ac I think a hot knife might be more suitable
