Has anyone ever used one of these?

It's a bit hefty on the price tag but if you have a lot of extruded foam to cut and carve for ditches, hills etc. I wonder if it would be worth it in the long run.

Frankly, I was worried about the fumes.

It makes a mess, but I can go pretty fast and accurately with the wood blade from a sawsall.

I bought the hot wire thing. Fumes are not all that bad, but its slow and not very accurate. I use a skeak knife. Its faster, cuts well, can be bent a little and the point makes nice rocks. I keep trying to use the hit wire, but nothing has worked very well yet.

Go to Ebay and type in foam cutter.

We had an industrial version where I worked that would cut through anything in a matter of seconds. You can also make one using a soldering iron and a piece of copper wire to test the pricipal. If you make the connections thicker and the area where you want to cut thinner the thinner area will concentrate the heat at that location.

Thanks all. I think I'm going to go with the steak knife. Sounds a little easier and safer.

hand cutting tools are usually faster, safer, and more controllable. And you won't kill off as many brain cells!
