What is a Hot Knife? (or All about the Hot Knife)

A hot knife is normally a hand-held tool with a handle and heated blade. Most hot knives are designed for cutting EPS foam (Styrofoam), or a similar type of insulating foam.

The blade heat on a hot knife is generated from either a transformer or an electrical circuit board. A quality hot knife can be manufactured using both technologies. One key to a quality hot knife is the interchangeable blade. A good quality hot knife blade should be thin and have a sharpened edge on the cutting side.

Demand Products offers a wide hot knife selection. We first offered the "Original Hot Knife" to the american trades in 1983. This model has the transformer built into the handle and has a constant heat output with an on/off trigger. Next we offered a heavy duty hot knife with the transformer in a separate housing connected by a 9 foot cord. This hot knife is called the Hot Rod hot knife and was designed for heavy-duty applications.

Next, we added the Craftsman Hot Knife. This hot knife is powered by a circuit board. Features include 16-click settings for heat output, plus an on/off spring loaded trigger.

We also have a Fabric Cutter Hot Knife designed for cutting polyester fabrics, webbing, ropes, etc. Both the Craftsman Hot knife and the Fabric Cutter Hot Knife come in their own custom case, along with a wire blade cleaning brush, hex wrench, blade, and instructions.
