Heavy Duty Foam Hot Knife

I was a little skeptical about buying this hot knife when the next step "up" was $299, but for $40, this fit my budget better. It works great! At heat level 4, it sliced through 4 in. thick insulation styrofoam (the cheap white kind) with no problem (Heat dial ranges from 1-5). You have to keep your finger on the button trigger as you cut and after a while it made my hand cramp up, but that wasn't a big deal. I'm making large foam scenery so I had quite a lot of cutting to do. Really worth the money and I highly recommend this hot knife!
