I bought this item to do a tool shadowing project for work and was using extremely high-density foam. This hot wire knife fit comfortably in my hand, the handle never got hot, and the results are very precise. I bent the wire while perfecting my technique, but I was able to bend it back and continue using it with no other issues. You just have to go slow and steady, using light pressure, letting the heat do the cutting. FANTASTIC PRODUCT! I will give this web-address to all of our new hires.

BTW...I love the fact that there is no high-voltage AC current present in the tool in your hand. This is a MAJOR plus for safety and confidence in using it. Its also a MUCH safer alternative to cutting foam with a knife. VERY little chance of slipping and hurting yourself with this tool.

I love this tool. It is very versatile and easy to use. It heats up quickly but my hand never gets hot. I bought this tool for simple shaping after being so frustrated with using a knife. This tool makes quick work of cutting and shaping any density of foam I have ever used. And the best part is there is no mess. I recommend this tool to everyone that is starting to sculpt with styrofoam.
